Plastic guide chain production method involves stages of cutting and/or forming links from a single extruded box-like profile

摘要

An extruded box-like profile of plastic or other deformable material is formed into interconnected links by: a) creating the joint connections of each link by forming and/or cutting stages; b) cutting both sidewalls from the underside and upper side to form inner(18) and outer(17) part wall of the joint with a joint trunnion(15) connected to the inner part wall; c) cutting(20) through the outer sidewall part to complete the trunnion; d) cutting through upper and lower faces of the profile between inner sidewalls.
