Title: Improvements in or relating to Machines for Winding Continuously Produced Tapes into Rolls
Inventor: REIFENHAUSER HANS
IPC: B65H19/22
Filed: 1968-11-27
Abstract: 1,190,850. Winding webs. REIFENHAUSER K.G. 27 Nov., 1968 [22 Dec., 1967], No. 56166/68. Heading B8R. A machine for winding tape 10 on to a tube 3 comprises a tube holder 2 including a driven roller 12 and a contact roller 13; a retaining roller 14 which can be swung in to secure an empty tube and tape in the tube holder; a magazine 4 carrying empty tubes 3 and provided with swivelling loading arms 8; swivelling winding arms 6 provided with clamps 7, e.g. in the form of expandible cones, to engage a tube 3, at least one of the clamps being power driven; and a cutter 5. In operation, the tape is wound into a roll 9 which is rotated both by the roller 12 and by the driven clamp or clamps 7 which have been moved to grip the tube 3. When a predetermined length of tape, set by a meter (not shown), has been wound on the roll the arms 6 swing into a take-off position 11; the loading arms 8 then transfer an empty tube 3 from the magazine 4 and hold it into contact with the web 10 and with the roller 12 so that the tube 3 starts to rotate. At the same time, the cutter 5 swings up to wrap more tape 10 round the empty tube 3 and to bring the tape into the cutting position. When the tape is cut the new end is blown into the gap between roller 13 and tube 3 by an air jet, the rear end is caught up and winding commences. The free tail is wound up on the completed roll 9 which is still gripped by the arms 6 and therefore still rotating. The arms 8 then release the tube 3 and return to the magazine 4 and the cutter 5 also returns to its starting position. The winding arms 6 then release the completed roll 9, return to the winding position, and engage the tube 3 to continue the winding process. The winding cycle is controlled by means of conventional automatic equipment.

Abstract: 1416247 Valves; fluid pressure brakes DAIMLER-BENZ AG 6 Dec 1973 [13 Dec 1972] 56593/73 Headings F2V and F2F A valve assembly for delivering fluid to a working chamber 20 and maintaining the pressure in the working chamber at a desired level comprises a sleeve member 29 having a central bore accommodating an element 30 also with a through-bore 32, and peripheral bores 31 each of which is connected to a high pressure chamber 15 and has the end which leads to the working chamber 20 controlled by a ball valve 39 and the other end sealed by a cylindrical piston 40, and a second valve 24 which controls the connection from the chamber 20 through the bore 32 to exhaust. Plates 37, 38 disposed on the element 30 abut the balls and pistons to form a pressure-balanced closure which may be biased closed by a spring as shown or the area of the pistons can be made larger than the area of the seats associated with the balls. Upon actuation of a plate 12 the second valve 24 abuts the element moving it to the right (as shown) to open the ball valves. Should the pressure in the working chamber rise above the desired level determined by the force applied to the plate 12, the second valve 24 is moved away from the element to afford relief. In a known embodiment described with reference to Fig. 1 (not shown) the closure member controlling connection between chambers 15 and 20 is integral with the element 30.

Register 36 and counter 32 are reset by switch 44 on arrival of the card at the sensing station and by the delayed output of gate 38 after each character sensed. The magnetizing and sensing heads could be moved relative to a stationary card 10.

[Class 102 (i).] Means for regulating the output of a fuelinjection pump for an internal - combustion engine comprises a handle 1 connected to the regulating rod 13 and engaging a quadrant 5. The stops 25, 26 determine the limits of movement of the handle for normal running, but the handle may be moved past these positions, by operating a detent 17, to either stop the engine or supply additional fuel. In a modification, the stop 35 limits the position of the pedal 29 for idle running and the engagement of the roller 56 with the wedge 60 limits the movement of the pedal to increase the fuel supply. However, the regulating rod 45 and pedal 29 may be moved further in that direction by compressing the spring 53. The wedge 60 is moved by a governor to reduce the fuel supplies at high speeds. The engine is stopped by removing the stop 35. Specification 408,760, [Group XXVI], is referred to.
