Title: Improvements relating to the stretching of film of synthetic linear organic polymeric material
IPC: B29C55/06
Filed: 1953-05-14
Abstract: <PICT:0740393/IV(a)/1> A travelling continuous web of film of synthetic linear organic polymeric material is continuously stretched longitudinally by opposed tensional forces acting lengthwise of the web over a substantial distance, the web being maintained between the forces in contact with a number of closely-spaced, parallel idler rolls, each freely rotatable on an axis at right-angles to the length of the web, and the web following a sinuous path over and under alternate idler rolls.  The opposed tensional forces are preferably provided by means of two groups of positively driven rolls, the number of idler rolls between them being such that the last idler roll is rotating at substantially the same speed as the fast rolls. Preferably also the clearances between the last positively-driven slow roll and the first idler roll, between adjacent idler rolls, and between the last idler roll and the first fast roll do not exceed 1.5-5 times the thickness of the film before stretching.  As shown in Fig. 1, the first group of five rolls A-E are the positively driven "slow" rolls, the second group of five rolls are idler rolls over which actual stretching is effected, and the third group of five rolls F-J are positively driven "fast" rolls.  All the rolls are 30 inches wide and 4.5 inches o.d.  The clearance between adjacent slow rolls and adjacent fast rolls is 4 inches, and that between the last slow roll and the first idler roll, between adjacent idler rolls and between the last idler roll and the first fast roll is 0.012 inch. In an example polymeric polyethylene glycol terephthalate is extruded to form an amorphous film 20 inches wide and 0.004 inch thick which is stretched as described above, the slow rolls being driven at a peripheral speed of about 9.7 yards/minute and the idler rolls and the fast rolls at a peripheral speed of about 26.7 yards/minute, giving a stretch ratio of about 2.75.  All the stretch occurs by the time the seventh idler roll is reached.  The stretched film is 18 inches wide and 0.0014 inch thick.  All the rolls are internally heated to give a surface temperature of 85-90 DEG  C.  The film material may be a polyamide such as polyhexamethylene adipamide or sebacamide or polycaproamide, vinylidene chloride, rubber hydrochloride, polystyrene, polyvinyl alcohol, polyvinyl acetals or vinyl acetate-chloride copolymer.  U.S.A. Specifications 2,071,250, 2,071,253 and 2,465,319 are referred to.

Abstract: 625,414. Loading refuse vehicles ; hoists, DEIGHTON'S PATENT FLUE & TUBE CO.. Ltd., and RIDDELL, L. H. June 1, 1945, No. 13769. [Classes 78 (iii) and 78 (iv)] In a refuse vehicle having lifting gear at the side or end of the body for raising and tipping a dust bin, the lifting gear comprises a hydraulic ram working within a vertical lifting tube 'adapted to impart motion to a lifting rope which passes around a pulley at the upper end of the tube and is directly connected to a holder for the dust bin, the arrangement being such that the travel of the holder is considerably greater than the relative movement between the ram and tube. As shown, the ram 1 is fixed to a bracket 6 on the chassis 3, and the tube 2 carries a pulley 5 around which passes a rope 7 having one end attached to the dust bin holder 15 and the other to the bottom of the tube, the rope also passing around a second pulley 5 mounted on the bracket 6. The holder 15 consists of a plate pivoted to a carriage 8 having runners 14 engaging vertical guide rails 9 secured to the body 4, movement of the carriage being limited by stops 22, 23. The plate is formed with a projection 21 which engages the side of the body and with a slot 16 through which the handle 17 of the dust bin 12 may be inserted and held by a pivoted catch 18 having a release lever 19. The top of the body is formed with an orifice 10 having a hinged lid 11 provided with pivoted arms 13 having outwardlyturned ends engaging the guide rails 9. As the carriage is moved up the guide rail, it engages the arms 13 and opens the lid 11, and when movement of the carriage is arrested by the stops 22, further operation of the lifting gear causes the plate 15 to turn about its pivot and tip the dust bin. During the latter movement, the projection 21 rides over the inner edge of the orifice 10 to prevent the plate being lowered unless it is in the vertical position, and two sets of teeth, one on the carriage and the other on the plate (not shown), engage to prevent disengagement of the dustbin. The pivot of the plate 15 is spring-loaded so that the plate and dustbin are swung back over the dead-centre position as soon as lowering commences. The arrangement is provided on both sides of the body as shown in Fig. 1, the body being tapered at the front for this purpose. As the only connection between the lifting gear and the body is the rope 7, the body may be tipped by hydraulic or other mechanism without difficulty. Specification 532,803 is referred to.
