Filed: 1961-03-28
Abstract: 917,235. Making wire fabric concrete-reinforcement mats. PITTSBURGH STEEL CO. March 28, 1961 [Sept. 26, 1960], No. 11271/61. Classes 83 (2) and 83 (4). [Also in Group XXIII] Apparatus for making hinged concretereinforcing wire mats comprises means for feeding ahead side-by-side two strips of wire fabric having parallel cross-wires secured to parallel longitudinal strand wires and with the cross-wires of one strip projecting laterally from its inner strand wire and overlapping the inner strand wire of the other strip, and means for wrapping the overlapping cross-wires around the overlapped strand wire to connect the two strips of wire fabric together. A wide band 1 of wire fabric made in apparatus 2 by welding cross-wires 3 to continuously travelling parallel strand wires 4, passes over an intermittently rotating drum 5 and the cross-wires 3 are then cut by a rotary saw 7 to form two strips of fabric. One strip passes over skids 20, 21 and the other strip is deflected towards the first by adjustable inclined rollers 34 so that the projecting ends of the cut cross-wires 3 of one strip overlap the inner line wire 4 of the other strip, so that they may be coiled around the line wire to form a hinged connection between the two strips by means 42. The hinged strips may then be cut to length, by means 43, folded together and removed. The means 42 includes a frame 44 adjustable in height by piston and cylinder means 47 carrying a laterally adjustable plate 62 on which is mounted a gear-case 70 in turn supporting in brackets 71, a pinion 72, Fig. 11. The pinion has a radial notch 74 and central rectangular passage 73 accommodating a rectangular slide 77, Figs. 9, 15, grooved at 78 and carrying a coiling head 79, with a radial notch 80, and normally urged away from the pinion 72 by springs 84. Forks 87 and 88 engage the crosswires 3 to stop forward movement of the wire fabric strips. The projecting cross-wire also engaging the coiling head 79 which then rotates so that a shoulder 85 thereon, in conjunction with an inclined surface of a block 89, wraps the wire around the inner line wire 4, which is guided in the notches 74, 80 and groove 78, the head 79 being forced back against the springs 84, Fig. 15. The pinion 72 is rotated by a gear 91 driven through one-revolution clutch and brake means actuated by solenoid means, every time the fabric band is stopped to permit a cross-wire to be welded to the strand wires. As soon as the cross-wire has been wrapped the hinged fabric is pushed above the stop forks 87, 88 by a bar 124, lifted by springs 134 and lowered by a cam 131 on a shaft 132 driven through a clutch 141, so that the fabric may be pushed forward.

Title: Improvements in or relating to the production of films
Inventor: GRIFFITHS LEONARD
IPC: B29C48/90
Filed: 1960-03-31
Abstract: <PICT:0903661/IV(a)/1> Thin walled highly crystallizable linear olefine polymer tubular film (which may subsequently, if desired, be slit into flat film) is produced by melt extruding a tube of the polyolefine, particularly polypropylene, 1 from the annular orifice 2 of an extrusion die 3.  The tube is stretched transversely by inflating it with air introduced through the passage 4 in the extrusion die 3 and at the same time stretched longitudinally by being hauled off from the die by nip rollers (not shown) at a greater linear speed than the speed of extrusion.  Immediately after the stretching of the tube is completed it is quenched by passing it through a passageway 10 which is interiorly bathed with water supplied from channels 13.  As the tubular film leaves the passageway 10, water is removed from its surface by a suction device 11 having a flexible sealing ring 12.  The passageway 10 is externally cooled by a supply of cooling liquid within the chamber 6.  Water is supplied to the channels 13 through a pipe 7 to reach a level 9 and overflows over the weir 14 into the waste channel 8.  Water is at the same time carried by the film between it and passageway 10.  The film may be extruded upwardly and caused to pass upwardly through a passageway to the bottom of which water is supplied to be carried through by the film. Polyolefine films produced according to the invention are more transparent than those produced by conventional film blowing processes.
