Abstract: Method of making multiple container carrier stock comprising strands of a resilient and deformable plastic material that has been extruded and fused in the molten or semi-molten state.

Abstract: Netting, made by bonding together crossing strands consisting of or containing thermoplastic material by means of individually moulded masses of thermoplastic material, is given enhanced bond strength by compressing the crossing strands together within the die cavities employed for moulding the thermoplastic masses. The improvement is particularly marked in the case of netting made from braided strands, for example of nylon, and intended for use as cargo nets. The compression may be applied by a pressure member, for example a fluid-actuated piston, mounted within the die. If desired, a pair of counteracting pistons can be used. After compressing the strands, the pistons may be withdrawn before the thermoplastic material is introduced or may be forced back by the entering thermoplastic material.

Abstract: An extruded integral plastics net structure comprising first sets of spaced parallel strands, second sets of spaced parallel strands extending transversely thereto, the sets of strands being joined together at all or certain of their points of intersection to form a net structure wherein the intersection points along any one strand are in the alternating forms of any two of the following: (a) integral masses of mirror image symmetry about the median plane of the net, (b) assymetrical junctions in which there is substantially only linear contact and adhesion between the strands and (c) symmetrical junctions having only linear contact with little or no adhesion between the strands.

Abstract: The method for manufacturing interconnected multi-packaging devices from elongated flattened plastic tubular elements is disclosed.

Abstract: Netting of small net size is economically made by forming a network of crossing longitudinal and transverse threads, bonding the threads together at the crossings by individually moulded buttons of thermoplastic material and moulding small masses of thermoplastic material (which may or may not be the buttons at the crossings) bearing integrally moulded elements radiating towards the centres of the mesh openings. The radiating elements may terminate close to one another or be joined together by an integrally moulded boss in the central region of each mesh opening. The radiating elements effectively block the mesh openings or divide them up into smaller openings without requiring correspondingly large and possibly excessive lengths of threads. The netting is suitable for security purposes, for example at expositions.
