Knotted wire fences are fabricated on specialised machines. The input material is typically galvanised steel wire. However, the quality of the input wire used by the Fence Producer is beyond control of the Machine Manufacturer. The problem is that wire strand breakages have been reported during fabrication and subsequent field erection. This is an issue for the Fence Producer because of the los...

The variations of nal mat thickness (basis weight) in the machine direction (MD) and cross machine direction (CD) on a crescent former are examined using a two-dimensional dynamic model. This two-dimensional model is extended from a previous one-dimensional model by including viscosity and a cross ow in the CD. The uid velocity pro les are parabolic in the MD and CD with no-slip conditions on t...

Paper furnishes often contain a mixture of a weak pulp with relatively short fibers and a strong pulp with relatively long fibers. Whereas increased proportion of the long-fiber pulp can be expected to impair formation, it has been unclear to what extent a change in formation through the pulp ratio affects the strength efficiency. (Strength efficiency is a measure of how well the strength poten...

This paper investigated the effect of tungsten arc melting current on microstructure and wear resistance coatings prepared from high-entropy powder-cored wire, FeCrMnCuNiSi1. A wire composition was drawn by wire-forming equipment, a FeCrMnCuNiSi1 alloy coating designed base material 40Cr fusion technique. The influence law mechanism were obtained through analyzing microstructure, physical phase...

Based on investigations with an ESEC thermosonic wire bonder, we report a novel ultrasound calibration method which consists of measuring in-situ the friction heat generated by the gold ball as it scrubs on the oxide of an integrated microsensor. This procedure can be carried out in-process using a dedicated testchip and a modiÞed clamping plate. The calibration dependence on the process parame...

In conventional wire drawing the diameter of a wire or rod-like workpiece is reduced by drawing it through a conical die. Dieless drawing of a wire or a rod is realized by a localized heating of the work piece. As heat source for example an induction coil can be used. Immediately after having passed the heating zone the work piece is cooled to restrict the heat input on very small region. By ap...
