发明名称 Method and apparatus for in-mould cutting of thermoformed objects withdrawable from the mould with the still partially connected residual web
摘要 <p>The invention relates to a method of thermoforming and partly cutting thermoforming objects, which comprises intermittently feeding a tape or plate (2) of thermoformable material to a thermoforming press (46); thermoforming and cutting the tape or plate in a mould (48, 50) to obtain at least one thermoformed article (51) surrounded by residual web or waste (57), wherein partial cutting is carried out by means of punch-and-die cutting means (52, 54) and cutting affects the whole outline of each thermoformed object (51) and has at least one discontinuity (55) which results in one or more tiny connection sections or witness beads (58) connecting each thermoformed object (51) to the waste (57). <IMAGE> <IMAGE></p>
