Safe travel: conveyor systems from IN-LOG | GÄMMERLER
Each postpress system requires a unique layout to accommodate various production, workflow, internal logistics, and space needs. A well-thought-out configuration can greatly impact a system's efficiency and ease of use. Our complete range of floor and overhead conveyors enables us to create the most efficient configuration for your needs. In particular, our unique "Spiral-," "S-," and "C-" conveyors allow us to safely transport the shingle stream at full speed through tight spaces. When the postpress area is not directly behind the press, our high conveyors bridge the gap between the folder delivery and the postpress area, leaving the floor space completely clear. Flow turns and bump turns realign products behind individual deliveries and in trimming lines. Waste ejection, a side jogger, and a squeeze roller ensure that only well-aligned and flattened products are processed.
Floor conveyors
Floor conveyors are the simplest way to transport a stream of shingled copies from the folder delivery to downstream machines for further processing. Since every system is different, the conveyor system must be highly flexible and adaptable to meet the needs of each project. A variety of conveyors with different functions ensures that specific requirements are met.
Standard: flat & round belt conveyors, length of 300-6000 mm, variable in- and outfeed height, up to 100m/min
Flow turns: 90° and 180° (other angles as an option), width 500 or 600 mm, variable in- and outfeed height, up to 100m/min
Divert conveyors: reject waste gates and divert gates, manual or pneumatic, variable in- and outfeed height, up to 100m/min
Walkway conveyors: collapsible conveyors, individual length, variable in- and outfeed height, up to 100m/min
Options: different width, moveable (mounted on casters), waste removal conveyors


90° spirals, 180° turning-, „S-" & „C-" conveyors
Most print shops see our “Spiral-“, "S-," and "C-" conveyors as a real advantage. What makes them so special? First, they can turn and raise or lower the shingle stream in tight spaces. Second, they safely transport the shingle stream. Copies are always held between two belts. Even when the shingle stream is turned 90°, the products do not fan out! The quality of the incoming shingle stream is equal to that of the outgoing stream. These conveyors make all the difference, especially behind high-speed web presses with multiple deliveries. Additionally, variable infeed and outfeed heights offer flexibility in conveyor system design.

OC/1120 – overhead conveyors
Do you need to transport products without wasting floor space? Our overhead conveyors can safely transport shingled streams over long distances. Upper and lower belts securely hold products in place, preventing relative movement. The customizable design allows for adjustable infeed and outfeed heights, turns on vertical up-and-down sections, and flexible changes of direction in the horizontal sections. This combination of features makes it possible to design virtually any desired configuration.

BT/1120 & BTD/1120 – bump turns
In a trimming line, products are processed in one trimmer with the spine first and in the second trimmer the spine to the side. Then, they are presented to the compensating stacker with the spine leading again. Printing presses with a single folder exit deliver tabloid products spine leading and magazine products spine to the side. In both cases, bump-turns are required to reorient the copies in the shingled stream. The BT/1120 bumps the shingled stream by 90° (left or right) while simultaneously rotating the copies within the stream by 90°. The bump turn changes the product orientation from "spine to the side" to "spine leading," or vice versa. The BT/1120 is a multi-format bump turn. It is equipped with a telescopic infeed conveyor and an adjustable stop and processes products ranging from digest to tabloid size. To safely reorient light and thin products at 90°, the outfeed belt can be equipped with an optional vacuum belt. The BT/1120 processes a single shingled stream but can also be configured as a double-stream BTD/1120 model that processes two superposed streams.

BTT/1120 & BTTD/1120 – bump turn / flow turn combination
A combination of a bump turn and a flow turn is required when processing and realigning products with different orientations. The bump turn and flow turn are mounted on a height-adjustable platform that allows either the bump turn or the flow turn to be active. In both cases the shingled stream is deviated by 90° to the left or to the right. Depending on the product and production type, the shingled stream either runs through the bump turn, resulting in a 90° change in product orientation, or the flow turn, which does not change the product orientation. The BTT/1120 processes one shingled stream, but it can also be configured as the BTTD/1120 double-stream model to process two superimposed streams.

SA/1120 – stream aligner (jogger)
A uniform, well-aligned, shingled stream minimizes jams and improves trimming and stacking quality. The SA/1120 stream aligner is a key component of nearly every conveyor system, ensuring that only properly aligned copies reach the trimming and stacking area. The SA/1120 has two long vibrating side joggers that gently align the copies in the stream. The left and right alignment units can be adjusted independently of each other, allowing for the alignment of non-centered shingle streams. The stream aligner can optionally be equipped with an electrical adjustment feature that is centered or off-center.

SR/1120 – squeeze rollers
A uniform, shingled stream of flattened products significantly improves stack quality and reduces the risk of jams caused by open, round folds. The SR/1120 squeeze roller removes most of the air from the copies, delivering a flat, even stream of shingled products. This optimizes the stacking process in the compensating and log stackers, as well as the quality of the bundles and logs. The squeeze rollers are easily adjustable in terms of both roller spacing and pneumatic pressure.

SS/1080 – Deserter (stream separator)
Web presses with special folder configurations can produce nested products that need to be separated in the finishing area. The SS/1080 deserter separates these products as they travel in a shingled stream. Depending on the application, the SS/1080 can be configured as a two-, three-, or four-out solution, depending on how many copies are inserted into one another. The two-out solution separates two nested copies into two streams, and the four-out solution separates four nested copies into four dedicated streams.

SS/1060 - Stream Lifter for the separation of two superposed shingled streams
A 16-page folded product delivered "closed head leading" (“Italienne”) can easily be transformed into two 8-page products with a simple head trim. The two 8-page products now lie on top of each other and travel in a shingled stream. If they are identical, they run into one compensating stacker. If the products are different, the upper copies must be lifted and separated to create two dedicated streams with two different products. The SS/1060 stream lifter can safely separate and slightly displace the upper copies. Next, the SS/1120 deserter completely separates the streams and delivers them to two stackers. This folding technique and postpress configuration allow to produce two different 8-page products while using the full web width, saving time and resources on the web press.


Trimming: single trimmers, double-stream trimmers, trimming lines & center cut trimmers
The best in-line trim – for inserts, newspapers, magazines or books (separation trim)
Trimming is one of our core competencies. For over 40 years, IN-LOG and GÄMMERLER have successfully built rotary knife trimmers under their own name and as an OEM. Our range of trimmers includes single trimmers with 1 or 2 knives, trimming lines with 3 or 4 knives, double-stream trimmers with 2 or 4 knives and center-cut trimmers, either for center separation trims or for center cut-outs. Today, we offer the most comprehensive range of in-line rotary knife trimmers. They impress with a unique trimming quality, are highly reliable and can be configured with either serrated carbide ring knives (standard) or segmented knives (optional, for special applications). Our dedicated configurations for heatset and coldset operations ensure that we best match the needs of each application.

Stacking and blocking: standard & high-end stacker, blocking unit
Great quality stacks – for retail, newspaper, magazine and book printing
Nearly all web presses are equipped with stacking equipment. These stackers count and collect signatures in either strapped logs or compensated bundles (stacks), which can then be further processed. Compensating stackers are ideal for "press-finished" products, such as inserts and newspapers, but they could also be used as an alternative to log stackers for magazine, catalog, and short-run book production.
Blocking units close coupled with a compensating stacker increase stack stability and quality. They are primarily used in insert printing to align and stabilize the bundles, creating perfect conditions for automatic palletizing.

Log stacker: for highest efficiency in the bindery
High quality logs – as work-in-process for magazines and books
Nearly all web presses are equipped with stacking equipment. These stackers count and collect signatures in either strapped logs or compensated bundles (stacks), which can then be further processed. Log stackers deliver compressed and strapped bundles, protected by two end boards. The copies between the end boards are flattened and well protected. Pallets with work-in-progress in the form of logs can be stored for extended periods and safely stacked on top of each other, resulting in reduced space requirements. Logs are the preferred solution for products that require further processing on a saddle stitcher or perfect binder in the bookbindery.

Palletizing: robots, mini-robots & cobots, pallet conveying systems
We safely get them on the pallet: loose & strapped bundles, logs, cartons & boxes
DManual palletizing, especially behind high-speed web presses, is labor-intensive. In search of higher productivity, more and more companies are considering automation. Robots are extremely reliable and flexible, and they can be used in different configurations and for different products. In our industry, we generally have to palletize stacks and logs, as well as cartons or boxes from one, two, or even more lines.
Our palletizing solutions are designed to meet a wide range of requirements, from simple palletizing of bundles from one line onto one pallet, to palletizing bundles and logs from four lines onto two pallets. Robotic palletizing reaches its full productivity potential when combined with automatic pallet handling. This involves feeding empty pallets from a magazine and placing them in the palletizing position, as well as conveying full pallets to the removal position.
All robots are equipped with intelligent software. In addition to operation and visualization, the software enables you to define individual palletizing patterns and flexibly define slip sheet placement. Do you need to execute palletizing orders in a specific sequence defined by your ERP system? Our optional order management software can connect to your production planning software, download the orders, and execute them in the specified sequence on the robot.
