Claims (12)

WHAT WE CLAIM IS: 7 7
1. An extrusion head for use in the manufacture of plastics articles which comprises two independent feed channels, each one leading to a set of one or more orifices, only one of said orifice sets being capable of being closed by means of a sliding device mounted exteriorly of all the orifices which is operable between open, closed and partially closed positions in respect of one of the orifice sets, the other of the orifice sets being incapable of closure.
2. An extrusion head according to claim 1, in which said orifice set which is incapable of closure comprises a plurality of orifices such that the material extruded through said set takes the form of rods or filaments.
3. An extrusion head according to claim 1 in which said orifice set which is incapable of closure is a single orifice of such dimensions that plastics material extruded through it takes the form of a flat sheet.
4. , A process for the production of an extruded plastics product, which comprises feeding plastics material through independent feed channels to a head as claimed in any of the previous claims, expelling the plastics as separate streams through the two orifice sets in said head, said plastics streams becoming united after their separate exit.
5. A process in accordance with claim 4, wherein different plastics material is fed through each channel.
6. A process in accordance with either of claims 4 and $ wherein the extrusion head employed is an extrusion head as claimed in claim 2.
7. A process in accordance with any of claims 4 to 6 in which a flat sheet is extruded through any one of the head's orifices.
8. A process in accordance with any of claims 4 to 6 wherein the said one orifice set is intermittently opened and closed to produce rods or bars of plastics material being transversely welded to the product that is separately extruded through the orifices of said other orifice set.
9. A process in accordance with any of the claims 5 to 7 in which the said orifice set which is capable of being opened or closed by the sliding device, is kept impartially opened and intermittently diluted thus producing from the head a sheet having transverse strips thereon.
10. A process in accordance with claim 5 wherein the head is operated to produce a product substantially as shown in any one of Figures 7, 8, 9, 12, 13, 14, 17, 18, 19, 22, 23 or 24 of the attached drawings.
11. An extruded plastics product whenever it is obtained by the process of anjr of claims 4 to 10.
12. An extrusion head as described herein, with reference to Figures 1 to 4, 5 and 6 and 11, 15 and !6 or 20 and 21 of the attached drawings.
