Title: Film stretching method and apparatus
IPC: B29L7/00
Filed: 1970-10-30
Abstract: 1371334 Film stretching apparatus AGFAGEVAERT 19 Oct 1971 [30 Oct 1970] 51780/70 Heading B5B Apparatus for longitudinally stretching continuous, organic polymeric, thermoplastic film includes (a) a pair of parallel, mirror-surfaced film support rollers 13, 14, closely spaced (e.g. not more than 10 mm. apart) so that portions of their surfaces form a channel-like reflector, having in cross-section, in planes normal to the roller axes, the shape of a V with inwardly convex sides; (b) means for continuously advancing the films 18 in contact with the rollers along a path which extends across the mouth of the channel-like reflector and for exerting stretching forces on the film as it passes across such mouth; (c) at least one infra-red heater 15 arranged for directing infra-red radiation through the film and on to the sides of said reflector, and (d) means independent of said heater for heating the upstream one of said rollers, and means for cooling the other of said rollers. The reflector-forming rollers may be freely rotatable, or positively driven, the upstream roller having the lower speed. As shown, the film makes contact with rollers 13, 14 over an angle of 45 degrees or less. Film-cooling roller 16 is so disposed as to contact the face of the film opposite to that which contacts the reflector-forming rollers, the distance between cooling roller 16 and the roller 14, measured between the notional lines of contact of the rollers with the tangent plane which the film follows between them) not being in excess of 5 cm. In operation, melt is extruded from extruder 11 on to the surface of quench drum 12, from which film 18 passes to supporting rollers 13, 14. Cooling rollers 16, 17 rapidly cool the film as it leaves roller 14, the time of contact with roller 14 being insufficient to obtain a rapid cooling of the film. For the same reason, the free distance of the film passed between rollers 14 and 16 and 16 and 17 is kept as small as possible. In Fig. 6, film support rollers 30, 31 are supported by an air-cushion between the rollers andthe half-cylindrical surfaces 32, 33 of support member 34. Surfaces 32, 33 are provided with a number of openings not shown through which pressurized air is continuously fed into the gap between member 34 and the rollers. This apparatus is useful in the production of films of widths exceeding 1 m. The stretching of polyethylene terephthalate films is described.

The sizing agent and chloroformate may be formulated as a single composition, e.g. an aqueous dispersion including a cationic emulsifier or a solution in toluene to ready formed sheets of, e.g. paper, semi-synthetic paper containing plastics, cardboard, board, or particle board by surface coating or immersion. Alternatively, for the treatment of paper stock, the sizing agent and chloroformate may be added simultaneously or as separate aqueous dispersions to the stock at different stages. The preferred sizing agents and chloroformate comprise hydrophobic organic groups, e.g. alkyl (8-40C), the examples disclosing distearyl carbamoyl chloride, methyl stearyl carbamoyl chloride and cetyl chloroformate. The ratio of sizing agent to chloroformate is preferably from 1 : 0À05 to 1 : 1. Reference has been directed by the Comptroller to Specification 1,392,746.

[Also in Divisions C1 and H1] In a turret machine (see Division H1) for making pressurized sealed magnetic contact units one of the work stations comprises a feeding assembly 180 (Fig. 4) which advances a continuous length of tubing 62a intermittently to a cutting assembly 184 (Fig. 12) which shears discrete lengths of tubing 62 and transfers them to the tube-holding assemblies 76 carried by the turret. The feeding assembly includes a slide 232 which can reciprocate vertically under the control of an hydraulic cylinder 182 and carries a plate 244 (Fig. 9) formed with a groove 250 to receive the tube 62a. The tube is clamped in the groove by a pawl 252 pivoted to the plate 244 at 254 and loaded by a spring 256, so that when the slide moves upwards the continuous length of tube 62a is advanced through the fixed cutting die 226 of the cutting assembly 184 until the required length projects above the die. The cutting assembly also includes a slide 202 which reciprocates horizontally under the control of a hydraulic piston 198 and carries the movable cutting die 214 and a tube supporting plate 220 upward movement of the slide 232 described above advancing the length of tube 62a through an aperture 214a in the die 214 and into a groove 220a in the plate 220. The slide 202 is held in its retracted position (Fig. 4) by a stop pin 228 which projects with slight clearance into an opening 230 in the slide so that when the piston 198 is advanced the slide moves forward a distance sufficient to clamp the projecting portion 62 of the tube but insufficient to sever it. The tube feeding slide 232 then moves downwards, the tube 62a slipping between the plate 244 and the pawl 252, and at the end of its stroke a projecting arm 270a engages the enlarged end 268 of the stop pin 228 and withdraws the pin from the opening 230. The cutting slide 202 can then move forwards causing the tube portion 62 to be severed and advances to the position of Fig. 12 ready for the tube holding assembly 76, which is lowered to pick up the tube 62 and then proceeds to the next station where the tube is inserted into the switch housing.
