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.
Claims7
In a netting of the type having mesh openings respectively bounded by spaced substantially parallel longitudinal threads, spaced substantially parallel transverse threads crossing said longitudinal threads at the corners of the mesh openings, and means interlocking and surrounding the crossing threads comprising buttons of thermoplastic material individually moulded about said thread crossings, the improvement comprising:
- means for subdividing said mesh openings comprising unitary subdividing elements of thermoplastic material formed integrally with small masses of the same material, said masses being moulded on the threads, said subdividing elements radiating from said threads toward the centers of the mesh openings;
- whereby to produce a netting having substantially closed openings of width substantially less than the parallel thread spacing while retaining the strength provided by said threads and without increasing the number of threads and thread crossing buttons.
