Title: Improvements in or relating to a machine for joining strip material end to end
IPC: B21C47/24
Filed: 1959-11-12
Abstract: 892,608. Seaming. USINES CHAUSSON S.A. DES. Nov. 12, 1959 [Dec. 11, 1958], No. 38435/59. Class 83 (4). In a feed mechanism for a press using metal strip, the strip is stored in reels and when a reel is empty the trailing end of the strip is joined to the leading end of a new reel by overlapping the new strip over the old strip and first folding the two strips together to a U-shape and then bring- ing the edges over and flattening them down. Strip from a reel 2 passes between a roller 7 and a pressure plate 8 which is connected to a device which produces an electric signal when the end of the strip leaves the roller. Mounted between the side members 9 and 10 of a frame 1 is a double-acting jack 12 connected to a cradle 16 which comprises side plates 17 and 18, spindles 19, 19a, rollers 20, 21 and a guide plate 22. Beneath the cradle is a fixed platform 23 and a pair of driven rollers 24 and 25. Fixed to the frame are guides 27 and 28, the distance between which corresponds to the width of the strips 2a and 3a and between the guides is a resiliently mounted shelf 30. Mounted in the side members 9 and 10 is a spindle 35, to which is pivoted a lever 38. Also mounted on the spindle 35 is a pivoting frame 39 which can be turned clockwise from the position shown in Fig. 2 to the position shown in dotted lines in Fig. 1. Secured to the pivoting frame is a shaft 42 to which are fixed two L-shaped squares 43, 45 and 44, 46, and a bell-crank which is connected to the lever 38 by a resilient linkage. When the lever 38 is in the position shown in Fig. 3, the arms 45 and 46 of the squares are under the frame 39. In operation the strip from the reel 2a is threaded over the roller 7, across the shelf 30, over the roller 25 and the fixed platform 23 and between the rollers 20 and 24, by which it is driven, through a device (not shown) which folds the edges up (Fig. 6) and then between the rollers 55 and 56 which complete the folding (Fig. 7). The strip 3a is passed over the roller 7, above the strip 2a and the end is held against the underside of the pivoting frame 39 by the arms 45 and 46, so that it is above the strip 2 but not in contact with it. The leading end of the strip 3a is under the roller 21. When the end of the strip 2a passes the roller 7 the signal generated causes the jack 12 to operate and brings the strip 3a down on to the strip 2a. The arms 45 and 46 enter slots 32 and retard the strip 2a by causing slight distortion. At the same time the strip 3a is driven by its contact with the strip 2a and the pressure of the roller 21, and the two strips pass simultaneously through the shaping device following the rollers 20 and 24 and are flattened by the rollers 55 and 56, thus forming a joint of sufficient strength to prevent the strips becoming separated during subsequent operations. The double thickness material is not discarded but is used to form components, which in the example described are radiator fins.

Title: Process for heat-setting fibres or films of polycarbonates
Inventor: FALKAI BELA VON
IPC: D01F6/64
Filed: 1964-09-22
Abstract: Polycarbonate fibres, fabrics and films &c. are heat-set at a temperature within \sB 2.5 DEG C of the temperature at which the tangent of the dielectric loss angle has its first subsidiary maximum.  The fibres &c. may be heat-set at a temperature within \sB 1.5 DEG C of the specified temperature.  In an example, a bundle of filaments of a polycarbonate based on 2:2-(4:4\sv-dihydroxydiphenyl)-propane is passed through a crossed roller drier maintained at 138 DEG C \sB 1.5 DEG C, the period of dwell in the drier being 5 minutes and the outlet speed of the bundle being 5% less than the inlet speed.  The optimum temperature of 138 DEG C is found on the basis of tg d  measurements at a frequency of 1 kilocycle per second of the material stretched at a stretch ratio of 4.2:1, the stretching dispersion region in the temperature range of 75 to 155 DEG C being found to have a maximum at 138 DEG C.  In the other Example a fabric woven from the polycarbonate fibres is heat-set for 35 seconds on a tentering frame at a temperature maintained within \sB 1.5 DEG C of the optimum temperature, which in this case is 150 DEG C.
