Design of a pile-yarn-manipulating mechanism

Abstract

A pile-yarn-manipulating mechanism for carpet weaving was designed and implemented. The pile-yarn-manipulating mechanism served to prepare the coloured pile yarn for a knotting mechanism according to a carpet pattern used as input. Such a mechanism required two auxiliary mechanisms (a holding mechanism and a cutting mechanism) to perform its function. A model for the pile yarn manipulating mechanism is presented herein. Important developments of weaving technology have been recorded. There are many carpet looms working at high speeds, but production methods of handmade carpets have not changed for several hundred years. The main difference between handmade and machine carpets is their texture type. The pile surface of machine carpets is produced by Jacquard's mechanism, but it is produced independently in handmade carpets by the weaver. There are basically two kinds of knot, namely the Turkish knot and the Persian knot.
