Universal forming shoulders are efficiently manufactured forming shoulders for bags with a flat bag width between 50 mm and 250 mm. Two different series are offered in our brochure “universal forming shoulder”. Besides price information the brochure gives the dimensions of each forming shoulder. Due to the pre-defined dimensions of the forming shoulder the design process of the machine can be faster.

Series ffcompact

Forming shoulder series ffcompact is developed for machines which offer only a little installation space. The infeed angle is rather small and causes more stress on the film material compared to a forming shoulder with a higher infeed angle. We suggest applying resilient film materials like mono-plastic films on these forming shoulders.

Series ffcomfort

This forming shoulder series offers an infeed angle of 45°. It is therefore also suitable for more sensitive laminated films. Due to the constant infeed angle we offer the option “infeed rolls” for this series. Infeed rolls align the film run to the surface of the forming shoulder in the most suitable way. By choosing this option two infeed rolls are attached to the infeed of the forming shoulder.
