Patent GB-705899-A (GB)
Abstract: 705,899. Making electric lamps &c. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 24, 1952 [Nov. 30, 1951], No. 29639/52. Class 39 (2.) To ensure the correct orientation of the leading-in wires of a mount assembly in machines for making electric lamps, discharge devices &c., the leading-in wires extending from the stem of the mount are made of magnetic material, and a magnet with its face oriented in a predetermined position is located at the station at which a lamp mount is presented to an open holder therefor. A magnet 1 of horseshoe shape is mounted in a non-magnetic block 17 at the lower end of a vertical rod 18 the upper end of which is clamped to the outer end of a horizontal arm 33 carried by a further arm 20 at the upper end of a vertically reciprocable rod 21. The rod 21 is raised and lowered by a cam operating in synchronism with the indexing movement of a turret 2 provided with mount holders 10 around its periphery. Each mount holder is associated with a radial bifurcated plate 16 located below the pivoted jaws 14, 15 and arranged to form a seating for the flared end of a stem tube 11. inserted manually with the exhausting tube 12 and outer ends of the leading- in wires extending down through the slot 16<SP>1</SP> of the plate 16. The mount 3 is inserted within the open jaws 14, 15, with one pair of leading-in wires 6, 7 towards the face of the magnet, so that the wires are drawn tightly against the magnet face and thereby determine the orientation of the mount before the jaws close upon the stem tube. The magnet is lifted upwardly before the mount is indexed towards the next work station. Alternatively, the face of the magnet may be shaped to conform to the curvature of the path of movement of the mount, so that the magnet may remain at a fixed position throughout the operation of the machine. To protect the operator and the apparatus from possible injury and damage during the downward movement of the magnet 1 the horizontal arms 20, 33 may be connected pivotally at 32 to allow the end 33 to swing upwardly should the operator's fingers be caught between the head 10 and the magnet. In a modification, Fig. 4 (not shown), an electromagnet is employed, and the face of the magnet is inclined at offset positions to engage correspondingly inclined leading-in wires.

Title: Band Feeding and Tightening Method and Device for Strapping Machine
IPC: B65B13/22
Filed: 1979-02-23
Abstract: A device for feeding and tightening a band around a package in a strapping machine comprises a feed roller (12) having a low-friction outer peripheral surface urged into contact with a high-friction outer peripheral surface of a reversing roller (11). A band (2) is fed between the rollers to a guide arch around a package, the feed roller (12) being driven by reversible drive means which at this stage is disengaged from the reversing roller (11). When the leading end of the band reaches a limit switch actuator, resistance of the band to further feeding causes slippage on the feed roller (12), so that feeding is stopped. The limit switch actuator also stops and reverses the drive means so that both the feed roller and the reversing roller are driven in the opposite direction to tighten the band around the package. When the tension in the band reaches a predetermined level, a second transmission system from the drive means takes over and drives the rollers at a reduced speed and increased torque through a differential reducing mechanism to complete the tightening. <IMAGE>
