Smart assembly using ultrasonic for the first time at Munich Fabric Start
Assembly by ultrasonic is a modern future-oriented and economical alternative to sewing. PFAFF Industrial has been dealing with this technology for more than 25 years.
The following innovations and product upgrades made the joining method “ultrasonic welding” interesting for the assembly in the garment industry:
programming of individual and entire seam sections
smooth and non-distorted seams or insertion of fullness
Cut & Seal:
welding and trimming in one operation
The process offers several technical advantages – no needle, no thread, no consumables. Additionally, the designer may refer to a multitude of seam designs, because the seam design is specified via the machine’s selected anvil wheel. PFAFF offers the customer a wide selection of anvil wheels.
The world debut was at the MUNICH FABRIC START in Munich (05. – 07.09.2017). For the first time ever, a complete piece of clothing (t-shirt) was assembled using ultrasonic at a tradeshow. Some weld seams were “taped” using a PFAFF hot-air taping machine. This welded tape could be used to seal the seam or merely as a design element.
The t-shirt was produced in full and live together with other innovative partners at the MICROFACTORY special show space.
The objective of the MICROFACTORY is to demonstrate to the industry an interlaced solution “from sketch to sewn garment”. On the one hand, approaches to the digitization of work steps respectively an entire process chain are to be illustrated; on the other hand, ideas and solutions on how to produce garments cost-effectively and efficiently in the future – even when the lot size is 1 and in Germany.
The following PFAFF-welding solutions were used to join/assemble:
Ultrasonic welding machine PFAFF 8312 Dual:
Joining the closing seams and trimming the edges (e. g. side seam and shoulder seam)
Ultrasonic welding machine PFAFF 8312:
Hemming operations (e. g. neckline, arm hole and lower hem)
Tape welding machine PFAFF 8303i:
Taping the closing seams (to seal the seam or as a design element)
