Karl Mayer has become a producer of complete systems for the production of packaging sacks and shading nets, and the company has extended its production repertoire in order to do this. In future, machine manufacturer from Obertshausen, Germany, will produce the ISO unit for cutting and stretching and continue to manufacture warp knitting machines for processing foil tapes. The FTL 1, FTL 2 and FTL 3 models are all part of the ISO film cutting and stretching unit. This unit was previously supplied by the bs Group. With the signing of a contract on Arpil 26, 2019, the machine rights, the spare parts business, and engineering expertise have all been transferred to Karl Mayer. The transfer of knowledge has been carried out on the basis of a tried-and-tested process.

Best of technology and a non-stop process
The ISO unit is located at the beginning of the processing chain for producing packaging and shading nets. The unit uses slitting bars to cut the tapes from a primary film. These are then stretch in a heating zone to produce monoaxial, flat tape yarns, which are fed to a raschel machine – reliably and consumption-dependent. The thickness, strength and delivery speed are all consistent and accurate.

The in-line system integration of the two production systems enables a delivery rate of up to 85 m/min to be reached. In this case, the tape yarns may have a minimum thickness of just 0.016 mm approximately and a width of 0.5 to 0.7 mm. The ISO system is also flexible, thanks to its modular design. Depending on the width, number of guide bars and gauge of the subsequent machine, as well as the desired tape width as it enters the machine, a number of ISO slitting and drawing modules can be combined.
