APPARATUS FOR TRIMMING ARTICLES MOLDINGLY FORMED ON THERMOPLASTIC SHEET AND PROCESS FOR OPERATING THEREOF

摘要

Apparatus and process for trimming articles molded on a plastic sheet and successively fed from a forming machine. A carriage (10) receives the article (b) to be suckingly held thereunder and is moved in a trimming zone (II), where a pair of longitudinal cutter devices (20, 20 min ), each having a stationary blade (22 min ) and an angularly movable blade (24 min ) are horizontally moved together from respective retreated positions for longitudinal cutting. Then, a front transverse cutter device (30) having similar pair of blades is raised up from retreated position for transverse cutting and then a rear transverse cutter device (30 min ) is similarly operated.
