Stitchmaster ST 100 - High-Performance Saddlestitching in
Formats up to A4+.
Featuring fast and easy makeready, the Stitchmaster ST 100 ensures efficient finishing of editions of 3,000 to 10,000 copies, and even longer runs with constantly changing formats. Operating at up to 9,000 cycles an hour and able to handle formats up to A4+, the robust and easy-to-operate Stitchmaster ST 100 is ideal for getting started in saddlestitching. It enables print shops and binderies to bring the entire production process in-house. Makeready is supported by a menu-based program. The settings for changing the format are shown one by one in the display of the stored-program control system. The entire saddlestitcher can thus be quickly and conveniently prepared for each new job.
The double vertical feeders of the Stitchmaster ST 100 are designed for a choice of sucker opening and gripper opening with high or low folio. With sucker opening, signatures with closed head or foot are opened by suckers. With high folio opening, the folio lip is at least five millimeters (0.20 inch), and with low folio opening the folio lip is at least eight millimeters (0.32 inch). Their modular design permits the use of up to four feeder units. This means that you can work with up to eight feeders, each of which accommodates a large pile volume.
Like the double vertical feeders, the cover folder feeder of the Stitchmaster ST 100 is also thoroughly designed for highly reliable saddlestitching in the format range up to A4+. Vertically loading of covers ensures particularly gentle production, because even with a large pile volume the pressure remains small. The format can be easily changed using a lock lever right on the cover folder feeder. The folding center, the sheet stop angle and the blast air and vacuum can all be finely adjusted on-the-fly. Integrated inside and outside scoring enables you to produce convincing results with different cover types flexibly and consistently. Either inside or outside scoring can be performed; change between the two is possible with just a few manual steps. Adjustment of the scoring tools to the cover thickness is done with the proven, play-free 1:1 FESTA quick adjustment.
The product is motionless during stitching, which yields optimum quality. The saddle chain is built to ensure smooth transport of the signatures. In its basic version, the stitcher has two stitching heads for standard 14-millimeter (0.55-inch) stitches. But up to four standard or loop stitching heads can be deployed - thus dependably meeting all requirements for products in the format range up to A4+. The stitching thickness is centrally entered, resulting in simultaneous setting of the wire length.
Due to its exceedingly robust, sturdy design, the trimmer of the Stitchmaster ST 100 copes well with heavy workloads. Products are trimmed while all of the conveyor belts stand perfectly still, thus almost completely eliminating any chance of marking. Up to 50 millimeters (1.97 inches) can be trimmed off each of three sides. First a precise side cut is made, followed by trimming of the head and foot. The side trim can be adjusted on-the-fly using a handwheel.
