From the Sector

At this year’s trade fair „SIMAC Tanning Tech“, PFAFF Industrial, together with DÜRKOPP ADLER and the regional agency DAP ITALIA, will present the latest solutions for shoe and leather processing. The fair will take place in Milan from 19th to 21st of February 2020. The joint booth is located in Hall 14, No. C09.

PFAFF News and Highlights:

PFAFF 3806
New integrated workplace for closing rub-down seams, such as heel-, front- and side seams on street shoes, slippers and leg boots. The PFAFF 3806 is equipped with two-thread chainstitch high-speed seamer head PFAFF 5487 with drop feed and variable top feed, high lift and adjustable top feed pressure, which ensures consistently high quality. Reinforcing tapes, which may be applied from top impart greater durability to the seams and prevent fine leathers from being pulled out of shape. Automatic control sequences (via parameter or photocell) reduce the manual handling and increase the process reliability and output.

PFAFF 1591
On the fair PFAFF INDUSTRIAL will show its electronic single-needle shoe post-bed machine with touch-control panel, new thread trimmer for short thread ends (< 5 mm) and new programmable thread tension. The key benefit of “programmable thread tension” is that suitable thread tensions can be applied for different material thicknesses and/or for different seam sequences (as these can be programmed on electronic machines). The tensions can be accessed and/or set via a knee switch or stitch counting. Manual setting of the thread tension, as is common with current shoe machines, is no longer necessary with the programmed thread tension.

PFAFF 8303i
The ot-air taping machine for welding continuous seams on water-resistant, waterproof and breathable materials will be exhibited as “shoe version” with very small/slim post from back. Effortlessly shoe uppers with small radii can be taped. The slim post and the differential feed (via two separate drive motors for the top and bottom feed roller) ensures absolute neat seams and a requested fullness und shaped parts.
 

Production units with latest joining technologies for the filtration industry

The core competence of PFAFF Industriesysteme und Maschinen GmbH is the joining of flexible materials. The company not only masters industrial sewing applications, but has also been an innovation leader in textile welding applications for decades. Depending on the material and customer requirements, customer solutions are implemented using the ULTRASONIC, HOT-AIR or HOT WEDGE welding methods. In addition to the classical industries such as 'clothing, shoes, home and car upholstery', the company has made a name for itself as a specialist supplier of production solutions for the filter industry. Whether it be filters for dry filtration (dust removal, air conditioning and ventilation technology) or for liquid filtration, such as pleating filters, tube filters, stocking filters, pocket filters, bag filters, etc., the articles must first be assembled. In close dialogue with the customer, PFAFF defines the right joining technology and implements this in the machine or production line.

With the brands PFAFF INDUSTRIAL and KSL, the company has the necessary experience in process engineering, electrical engineering, automation technology and robotics to meet customer requirements for reliable, partly fully automatic solutions. A fully automatic production line for the manufacture of filter bags (with longitudinal seams) for an Asian customer is currently being manufactured in Kaiserslautern/Germany. At the heart of the system are the exchangeable hot-wedge welding and 3-thread chainstitch sewing units. Depending on the application, these can be implemented in the manufacturing process in just a few minutes. The raw material is unrolled, precisely formed and quickly and reliably fed to the sewing or welding unit. After joining, the 'tubes' are cut (filter length selectable via display) and automatically ejected. Optionally, the parts can be labelled using a printer. Depending on the material, the plant reaches a production speed of 10m/min.
