An apparatus for the provision of transverse weld seams and transverse detaching cuts, or of transverse detaching weld seams, on an intermittently pushed and/or intermittently carried tubular or semi-tubular web of thermoplastic synthetic resin and for stacking the detached sections, consists of a transverse welding and transverse detaching station for detachment of sections provided with bottom weld seams and any leading head weld seams from the web and a stacking station, which is provided with means for retaining or fixing the supplied sections. In order to provide for an efficient cooling of trailing weld seams on the sections without causing any sticking together of the sections during stacking adjacent to bottom weld seams, there is a tube, adapted to rotate about a transverse axis, provided between the transverse welding and transverse detaching station and the stacking station, the enveloping cylindrical outline thereof being constituted by at least two rods or parts of the wall, and which is adapted to be driven in rotation in step with welding through an angular increment which amounts to a fraction corresponding to the number of rods or the like of one revolution. In step with such deposit there is a free path for the web pushed through gaps in the tube between the transverse welding and the transverse detaching station and the stacking station.
