Abstract

Apparatus for longitudinally and transversely trimming articles moldingly formed on plastic sheet which is brought by means of a pair of clamp chains between longitudinally movable pointed tip knives and longitudinally extended holder members as well as transversely movable pointed tip knives and transversely extended holder member respectively held in retracted position and then trimmed by moving said knives and holder members to forwarded position and by moving said knives. Said sheet is formed in advance with transversely and longitudinally extended ridges so that said moving knives cannot sever the sheet at said ridges, whereby trimmed articles fall down by gravity and waste portion kept in one piece is brought out by said clamp chains to be collected. In order to attain correct trimming, said sheet is formed in advance further with additional transversely and longitudinally extended ridges respectively beside and in parallel with lines to be severed so that each rib mounted beside the concerned knife and extended in parallel with the knife moving direction fits in the concerned additional ridge of the sheet from the reverse side.
