A B S T R A C T This invention is concerned with the tack spinning of materials and has particular reference to the formation of tack spun materials by applying a thermoplastics polymer to a backing or carrier sheet to form a pattern or layer thereon and then heating the layer and contacting the layer with a second surface whereby separation of the carrier from the second surface results in separation of the thermoplastics polymer within its plane to draw fibres therefrom on progressive separation. The preferred embodiment of the invention involves two backing sheets prepared between a pair of nip rollers to form a sandwich structure with a layer of thermoplastics tack spinnable material and separating the same on the downstream side of the nip to provide the fibres disposed substantially transverse to the plane of the carrier sheet. The invention also describes novel apparatus for performing this operation.
