Abstract

An extruded plastics tubular film 10 having integral ribs 12, 14 of a different colour or a different chemical nature is cut along line 16 to form bag material, the ribs being interfitted, see Fig. 2 (not reproduced), to close the bag. Extrusion is through a die head having a main extrusion channel 26, Fig. 3, fed via coupling 36 and chambers 30, 32, and auxiliary channels 40, 42 fed via coupling 54 and bore 38 and communicating with chambers 44, 46. In operation material extruded via channel 26 forms tubular film 10 and a second material which accumulates in chambers 44, 46 is shaped by orifices (50), Fig. 4 (not shown), and 52 in a die plate 48 and is led into contact with the film to form the integral ribs 12, 14. The film may be cooled and inflated via bore 58, Fig. 3, a breaker plate 28 is provided, and it is stated that a ribbed sheet may be extruded instead of a tube.
