Abstract: The present invention concerns a storage structure for yarn bobbins and it comprises a plurality of storage units having support devices of the bobbin. Such storage units are distributed in a plurality of stationary deposit equipments. The storage units contained within each stationary deposit equipment are movable along an annular path. The stationary deposit equipments are vertically superimposed in groups. The groups of deposits are arranged in lateral, side-by-side relationship, thus defining a vertical surface of loading and a vertical surface of unloading, which are accessible from devices of loading and unloading, respectively.

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.
