Tufting process and tufting device suitable for implementation of this process

摘要

A tufting process is provided whereby one pile length is cut from a pile material which is to be joined to a backing material by means of a cutting edge after the formation of each loop. Provision is also made for the cutting process to be effected by means of the vibrational cutting movement of a cutting edge, in particular with the aim of improving the cut and reducing wear. In order to implement such a process, a tufting device is provided which incorporates a row of side by side loopers. The loopers move to-and-fro for the purpose of looping the pile material. Each looper includes a base installed in a looper block. A shaft extends from the block and has a nose for collecting the yarn on its front end. The shaft further incorporates a cutting edge configured so as to perform the cutting process. Each looper is adapted to be coupled with a vibrating drive which superimposes a vibrational motion on top of the to- and-fro motion.
