With a total of 117 participating nations, around 63,000 visitors and 2,300 exhibitors, the global textile business was back in Frankfurt/Germany from June 21-124, 2022, for the Techtextil, Texprocess and Heimtextil Summer Special. On a stand of 800m², Pfaff Industrial and KSL, together with Dürkopp Adler GmbH (DA Group), Bielefeld/Germany, presented multiple innovative solutions for joining textiles and leather.
Pfaff Industriesysteme und Maschinen GmbH (Pfaff Industrial), Kaiserslautern/Germany, demonstrated its new Pfaff 3834 programmable sleeve-setting machine. A thread tension control has been developed that automatically adjusts the thread tension to the material thickness currently being handled. The material thickness detection and real-time adjustment (360° monitoring) feature ensures optimum stitch formation, even when sewing over cross-seams and interlinings. By using the roller presser (running close to the needle), the material can be worked in with pinpoint accuracy. Optimal work with a clear view of the sewing material is assured. The new machine guarantees smooth seams and even stitch formation, especially when sewing sensitive and difficult fabrics.
The new Pfaff 1591 is a machine with thread tension regulation, which automatically adjusts the thread tension to the material thickness being handled. Material thickness detection and adjustment in real time (360° monitoring). Additionally, the machine has a short-thread cutter and a “neat seam start”, which makes the thread nest of the upper thread disappear.
An expansion of Pfaff Industrial’s “chain stitch inline” construction kit, the new Pfaff 5696 was presented with a narrow 25 mm column. The machine is offered with a standard and a long-arm version (700 mm clearance). It is used for 2-needle decorative seams on large, bulky and voluminous parts (dashboards, consoles, leather, technical applications etc.). The mirrored hooks are an innovation ensuring a straight stitch position of the parallel seams with no saw-tooth look.
The Pfaff 3688 pocket-setter builds on the successful and flexible concept of the 3588 and expands its range of applications. It features a simplified, intuitive operating concept plus electronically controlled thread tension, direct drive, carriage feed with servo drives, network connection (Pfaff Connect) and adjustable vacuum strength. The fullness function and the automatic bartack reinforcement, which enables high-quality processing of delicate stretch fabric, are other new features.
Pfaff Connect represents a network connection for sewing and welding machines. Thanks to the VNC server, integrated into the control panel, all machine functions can be viewed and changed at any time via a network. Using the “BoxPc” option, all machine and production data can be read out and displayed on a dedicated website assigned to the machine.
Unique in controlling the basic process parameters, such as air flow, pressure, temperature and speed, the Pfaff 8303i has been the state-of-the-art seam taping machine. Now the company has added the 3D axis nozzle position. The new Pfaff 8333 allows all relevant determining factors to be preset to certain welding programs.
With the KL 500 robotic unit, DA Group member KSL, Bensheim/Germany, presented a complete 3D sewing cell, as used in production plants for the manufacture of vehicle dashboards. Entire dashboards are stitched with high efficiency, process reliability and repeatability. The unit includes robot, a Vision system, component holders, rotary indexing table, sewing heads (2-needle double chain stitch - special post), protective fence concept etc. Various products can be manufactured with minimal conversion effort. The only things that need to be changed are the component holders and possibly the sewing head.
The KSL 352 is a solution for sophisticated safety, functional and decorative seams. The sewing head with horizontal hook, which is tailored to the machine, enables the option of a bobbin changing system. Many new technical refinements have been implemented in the KL 352, such as: Thread tension and foot height can be individually set for each seam section. These technical innovations increase process reliability and ensure a high-performance in the multidirectional sewing process.
The CNC sewing unit KL 110 with rotating head for servo-controlled continuous or intermittent free programmable sewing of head-airbags ensures high process reliability and maximum performance. The rotating head ensures high efficiency and quality for tangential multidirectional sewing operations. The KL 110 was presented with Vision System, an intelligent system that compensates for tolerances which have been developed. These arise due to the shrinking of materials and tolerances, including during the punching of perforations. Specifically, the Vision system compares an image of a master example with the image of the piece mounted in the sewing template. By means of individual measurement points, the entire seam pattern is automatically corrected within the sewing program. Process reliability is significantly increased, waste is reduced. The automatic template changer system ensures a full-overlapped workflow.
