ABSTRACT:
An apparatus is disclosed for the formation of yarn turns on a warper support. The yarn is loaded onto a support intended for a samples weaving loom, in a warper utilizing a suitably programmed thread-by-thread warping system. The apparatus includes a support for thread turns and a thread holding member with a thread-guide driven into continuous motion for drawing a thread along and forming the thread turns on the support. A thread device for retaining and presenting and recovering thread from the thread holding member is provided which includes a plurality of members each of which handles thread coming from a creel. A release system for the release of thread from the thread-guide of the thread holding member is provided. The release system has a plurality of release devices associated in close proximity to the members of the thread device. Each of the release devices is selectively controlled to operate the release of at least one of the threads. One of the release devices is disposed immediately downstream, with respect to a direction of motion of the thread holding member, of the plurality of members. The provision of the plurality of release devices and the location of these in close proximity to the members of the thread device avoids the considerable double length of yarn and avoids time to recover this which is requires in the prior art devices.
