Abstract: A manufacturing machine in which the pressing mechanism (20), for rolling the strips of material (2) against the forming mandrel (3), and the traction mechanism (10), for moving the shaped strips of material along the forming mandrel (3), are distinct in order to separate these two functions. The pressing mechanism (20) comprises a plurality of deformable press rollers (21) mounted free in rotation about their axis and distributed radially around the forming mandrel (3) so as to fit the periphery of the mandrel. The traction mechanism (10) comprised several traction belts (11) carried by drive rollers (12) positioned downstream of the pressing mechanism (20).

Abstract: The invention relates to an interlacing device which can be used automatically to interlace long products on a transport pallet in an economical and optimum manner, which can be adapted to tubes of any length and which operates concurrently with the palletizing machine. The inventive interlacing device (10) is characterized in that it comprises at least one interlacing gantry (11) which extends parallel to the palletized products along at least part of the length thereof and which comprises at least one wire guide (20), the wire guide being fed by at least one interlacing (12?) link reel (12). The aforementioned interlacing device (10) also comprises drive means (14) which are connected to the interlacing gantry (11) in order to move same alternatively between at least two end positions such as to move the guide wire (20) alternatively from one side of the transport pallet (7) to the other in at least one interlacing plane (P) which is essentially perpendicular to the palletized products (2).

Abstract: The object of the present invention is to recondition cardboard or similar tubes with deformed parts, notably at the ends, whilst avoiding the usual milling techniques and without removing any material. The deformed parts of each tube (1) are recalibrated to their initial thickness by being rolled between pairs of rollers (15, 20), of which at least one is driven in rotation. The tube (1) is then supported only by the rollers. Each internal roller (20) can be mounted on a movable support (18) which brings it into its working position in the tube. Application for the reconditioning of tubes serving as supports for textile yarn reels.
