Abstract: A spool loading and centering device for loading and centering spools on support plates in order to send the said spools for winding. Each support plate has a rod and centering and restraining springs. The spool loading and centering device includes a spool presentation and centering device for presenting and centering of each spool onto each support plate and a spool fitting device for fitting the tube of each spool onto the top of the rod of each support plate. The spool fitting device travels a path which corresponds to fitting of the spool, as far as its base stop on the support plate.

Abstract: A device for sequentially loading tubes in a spinning machine wherein the tubes are fed by a tube orientating device. The device disclosed includes a duct for guiding the fall of the tubes and provided at its lower end with a shutter which loads one tube at a time onto the pegs of the spinning machine doffing belt by withdrawing it from a stack of tubes accumulated within the duct to form a buffer stock.

Abstract: A winding machine and method of operating the same in which prearranged packages of yarn are formed during spinning by inserting the yarn end through the upper cavity of a yarn tube by a package arranging device and the prearranged packages are conveyed in a vertical or substantially vertical position to a package carrier wherein the package carrier is maintained fully loaded with the prearranged packages.

Abstract: A device for sequentially loading tubes onto pegs on the doffing belt of a spinning machine having a tube orienting system which includes a duct for guiding the fall of the tubes, and a mobile dispenser comprising a plurality of compartments which receive the tubes from the duct load each from the duct and also load each tube onto the pegs of the doffing belt.

Abstract: The present invention relates to a device for correcting the variation in tension of the thread as it unwinds in a spooler, which is designed to wind thread at high speed. The device comprises two elements which act as unwinding accelerators, one fixedly located above the top of the cop. The moveable element pivots between an inoperative position spaced apart from the cop and an operative position coaxial and surrounding the cop so as to place itself concentrically to the cop and in a lower position at the moment when there is a reduced minimum quantity of wound thread on the end part of the cop being gradually unwound.
