Abstract
A hand manipulated tube which can be axially stacked and is able to sustain bobbins that can be stacked, one against another, at least for doubling and twisting operations comprising an outside section which is at least partially elastic radially and disposed circumferentially, and which bears protrusions positioned lengthwise in respect of an end face of a portion of the tube, and which extend radially outwards, an inner circumferential seat in the portion of the tube positioned in respect of the other end of the tube whereby the partially radially elastic side cooperates with the inner circumferential seat for the positioning of two axially stacked tubes, axial guides within the tube and possibly a radially guiding and tensioning element between one tube and another.
