Abstract: 1491805 Winding up continuously supplied cable or tubing MAILLEFER SA 12 Feb 1975 [19 Feb 1974 4 July 1974] 5912/75 Headings D1J and D1T A cable or tube 1, Fig. 2, is fed via a driving device to a guiding and shearing mechanism 9 and thence to one or other of two winding mechanisms 2, 3, there being means 23, 28 for pulling a freshly severed end of the cable or tube away from the guiding and shearing mechanism 9 and onto a winding mechanism. Guiding and Shearing Mechanism 9. In Fig. 2 the guide block 16 has two through bores 17a and 18a. one for each of the wind-up devices 2, 3. Slidable along the block 16 is a switching block 19 with a single through bore that can be aligned with either of the bores 17a, 18a. When the drum 2 is full the block 19 slides away from the viewer in Fig. 2 to shear the tube or cable passing through the bore 17a and carry the sheared leading end into alignment with the bore 18a through which the cable or tube 1 is then fed by the aforesaid driving device. In a modified construction there is only the block 19 with a single through bore. A saw cuts the cable or tube downstream of the block 19. Cable Pulling Means. To pull a freshly cut cable or tube end from the block 16 to a wind-up drum there is provided for each drum a cable pulling device that can comprise a wire 28 connected at one end to its associated drum and at its other end to a grasping member. In Fig. 3 the grasping member is a plate 23 equipped with two grasping blades 25. Fig. 2 shows how the plate 23 is held against, say, the through bore 18a by a pivoted lever 26. When a pipe or cable emerges from the bore 18a it passes between the blades 25 of the plate 23. The lever 26 is then raised and the drum 3 rotated to wind up the wire 28 and so pull the cable or tube through a traverse mechanism 6 and onto the drum 3. Fig. 4 shows a modified grasping member 32 that is V-shaped. In use the two arms of the V-shape are closed together and the member 32 is held against a bore 17a or 18a. When a cable or tube end passes through aligned holes in the two arms the member 32 is released so that the two arms spring apart and grip the cable or tube 1. The wire 28 is then wound up as above.  In a further grasping member, Fig. 5 (not shown) a tube is provided containing blades similar to the blades 25. In a further grasping member, Fig. 6 (not shown), the grasping member is in the form of a rod (40) that carries barbs (42) so arranged that the rod can be inserted into a tube end but cannot be retracted therefrom. Winding up Electric Cables. In order that a wound up cable shall be accessible' at both ends, the pulling cable 28 can pass through a hub flange of a windup drum 2 or 3. The cable 28 is then wound up by means of a winch that rotates with the drum 2 or 3; or by means that does not rotate with the drum 2 or 3. In the latter  case the pulling means is severed once the leading end of the cable has been drawn through the hub flange.  Counting.  The apparatus may include a running-length counter for measuring the length wound-up. When a predetermined length is attained the change over from one bobbin to the other is automatically effected. Wind-up Means. The wind-up means are shown as being removable flanged drums 2. 3. In certain instances they may be cylinders permanently mounted on their supports, the product then being wound in the form of coils which are then removed when a winding is completed.
