Method of making plastic plate with rolled edge rim |
摘要 |
Molded plastic plates having a rolled edge rim and a method of rolling the edges of molded plastic plated. The plastic plates are pre-molded with lugs that project outwardly from the sides of the plates. The lugs of one plate contact the rim of the next successive plate in a stack of plates to create a gap between the plates stacked one on top of another. The gap allows each individual plate to be picked up by the threads on a plurality of threaded rollers which press on the rim of the plate to form the rolled edge.
