Problems solved by technology

However, in doing so, the twisted portion of the web is pulled forcefully in the opposite direction, allowing it to deform into a position where it cannot properly obtain or maintain the honeycomb shape
Thus, it is difficult to twist the thread and weave a honeycomb network with uniform and consistent shape and strength

Abstract

A device for twisting plastic wires to form a plastic open mesh net comprises a front twist mechanism and a back twist mechanism which have corresponding pairs of front and back thread-holes for receiving plastic wires to be twisted. Each couple of a front thread-hole and a back thread-hole is connected by a corresponding heat-conductive thread guide, preferably in the form of a pipe, which provides a uniform heating of the plastic wire which is guided therein. A machine for manufacturing a plastic open mesh net comprises a holding device downstream of the twisting device to maintain a uniform shape of the just formed open mesh net.

Description

technical field [0001] The present invention relates to the field of devices and machines for the manufacture of open mesh nets. [0002] In the context of this specification, the term "honeycomb network" is also used to denote an open mesh network in which several threads are connected by twisting adjacent threads to each other to form a network whose openings resemble honeycomb cells. However, the invention is not limited to hexagonal cells or double twisted meshes. [0003] The invention has been developed with particular attention to devices capable of twisting plastic wires and producing open mesh or honeycomb networks. [0004] In the simple construction of the invention, each plastic thread is heated uniformly just before twisting. The invention also simplifies and facilitates the threading operations of plastic wires and, additionally, in the field of manufacturing cellular webs, the device helps to maintain a consistent cellular shape. Background technique [000...
