Forming expanded grid angle section in PVC - has form tools mounted on endless chains to heat set required shape

摘要

An angle section made of expanded grid material in soft PVC is guided from the drawing stage to a setting process where it is held to a right angle shape by matching form tools. The tools can be arranged to be attached to an upper and lower endless driving chain and to slide on guide rails. They can be independently adjusted in the vertical and horizontal direction. USE/ADVANTAGE - The process ensures that a straight profile is maintained and that the section has the required radius in the corner.
