Plastic Extruders

The alignment of several materials to each other to be cut, doubled or even centered in the machine, and to manage the finished width to within acceptable quality thresholds. The solution: For example knife guiding directly at the cushion calender to cut and double the cushion directly on Innerliner material, which is produced by a Roller Head calender.Also the use of edge trimming devices behind the cooling, ensure that the shrinking process of the material will have stopped. These cuttings are effectively guided with closed-loop CCD cameras, which measure the final width and control the knives.Strip guiding systems are also part of these machines, as well as guiding by V-marks. Guiding by V-marks means centering of not trimmed materials by a triangular shaped mark in the center of the material. Benefits: Possible recipe change during full production Shrinking of material, while cooling, is not longer a operator experienced value.
