Abstract
The invention is concerned with a device for replacing cops with spools in a textile yarn spinning and winding system, comprising at least one main structure moving horizontally across at least one row of spool holding spindles for holding spools. The main structure includes an assembly for cutting and reattaching the yarns to the spools which is rigidly attached to said the main structure, and at least a spool changing assembly rotatable about and movable along a vertical axis. The thread cutting and reattaching assembly is movable vertically independently of the spool changing assembly, the spool changing assembly carrying at least two horizontal rigid elongated bodies in relation to their depth, anchored cantilever-fashion, the rigid bodies having a suitable cross-section to engage with the inside diameters of the spools. The thread cutting and reattaching assembly and the axes of the rigid bodies extend in a substantially vertical plane during the steps of cop loading on and spool discharging from the rigid bodies, whereby the steps and the operations of thread cutting and reattaching can take place with one positioning of the main structure in front of each of the spool holding spindles.
