Abstract: 1,258,743. Extruding polymeric sheet material. O-B. RASMUSSEN. 30 Dec., 1968 [29 Dec., 1967], No. 59204/67. Heading B5A. An extruded polymeric sheet material comprises lamellae 1, 3 of the same or different polymers, lamellae 1 being bonded together to form one surface of the sheet and extending to intermesh with lamellae 3 which are bonded together to form the opposite surface of the sheet; the portions of the lamellae which intermesh being cleavably bonded together in the core of the sheet. By cleavably bonded is meant that the bonding may be removed without substantial damage to the lamellae or affecting the surface bondings; thereby the sheet may be divided into two parts each having a bonded surface and a textile-like surface. The lamellae 1, 3 may be of dissimilar and incompatible materials, e.g. polyamide and high density polyethylene or polyester, but preferably are similar, with a second material, which may also be polymeric, being situated between the intermeshing portions in the form of further lamellae and constituting the cleavable bonding. Lamellae 1, 3 may be of a prepolymer cured after extrusion, e.g. a polyisocyanate/polyol mixture. A preferred second material is a polymer-in-polymer emulsion, one of the constituents forming a strong adhesive bond with either or both of lamellae 1, 3 and the other constituent promoting splitting of the second material into a fibrous form. Preferably with this material the sheet is divided whilst the second material is molten and the lamellae 1, 3 are solid. The textile-like surface(s) are thereby provided with a fibrous nap. The second material may be in the form of a paste, an expanded material, the expanding agent being added before, during or after the extrusion, a polymeric material containing an oil which bleeds out on solidification, and initiation of the division of the sheet may be by drawing, rolling, impacting, bending, or acoustically, or by chemical action, e.g. partially or completely dissolving out the second material. The apparatus for producing the sheet material is essentially the same as that described in Specification 1,258,393, the main modification being the slot distribution, Fig. 3, where lamellae 1 and 3 are formed by extrusion through slots 4 and 6 respectively and the lamellae of the second material are produced by extrusion through slots 5. Furthermore slots 4 and 6 may taper towards the centre of the slots. The surface bonding of the material may be formed or improved by the provision of combs in the outlet slot (10), Fig. 2 (not shown), which draw out tentacles from the surfaces; see also Specification 1,171,111, or the injection into the surfaces of transverse lamellae through orifices in the teeth of the abovementioned combs, see Specification 1,199,724.
