Abstract

A pair of plastics closure strips for use in a bag, each comprises one of interengageable male and female closure profile portions (20, 22) on one of base portions (21, 23), which are simultaneously extruded from a die body having profile channels (42a, 42c) (communicating with die profile outlet openings (52, 63) for extruding the profile portions, and base channels (43, 42b) communicating with die face outlet openings (45, 66) for extruding the base portions. The channels are adjacent to each other near the die openings and separated by a portion of the die body which terminates short of the outlet face of the die, so that the extruded profile and base portions join together before exiting the die body. The portions may be of different plastics materials. Each channel has a control orifice (56, 57, 43, 48) and an adjustable valve control (58, 59, 44, 49). The profile portions may be extruded from the die in facing relationship. <IMAGE> [GB2046660A]
