Title: Laminated non-woven fabric and method for manufacturing the same
IPC: D04H11/08
Filed: 1960-04-04
Abstract: 950,068. Laminates. M. T. HOFFMAN. April 4, 1960 [April 8, 1959], No. 11832/60. Heading B5N. [Also in Division D1] A non-woven laminated textile product adapted for use in wearing apparel comprises a foundation layer bounded by a pair of parallel surfaces and a lining layer formed by relatively loose fibres of which a portion projects through the foundation layer and has ends situated on opposite sides of the foundation layer. The foundation layer is formed by a layer of randomly oriented fibres defining interstices between the fibres thereof and having elastic fibre-connecting tie means localized at discrete points and predominantly at the crossover points of fibres, thereby imparting isoelasticity to the foundation layer. The fibres of the lining layer project through a portion of the interstices of the foundation layer and are clamped in position by the action of the isoelastic forces in the foundation layer. The term isoelastic indicates that the material has substantially the same elastic proper ties in any direction in its plane. The foundation layer may be made by superposing several thin carded webs of natural or synthetic fibres in angular relation and spraying with an aqueous dispersion of a rubber, drying and vulcanizing. As shown, the foundation layer 2 is unwound from roll 1, a non-elastic open fabric or netting 5 from a roll 4 is laid upon it, and a mat or fleece 7 of relatively loose fibres from a roll 6 laid upon the open fabric. The superposed layers are then needled together by the needle-loom 8 to form the finished fabric 9. The relatively loose fibre may be deposited from a garnetting machine instead of being drawn from the roll 6, or the open fabric 5 may be omitted. A second layer of loose fibre may be needled to the other side of the foundation layer. The rubber binder of the foundation layer may be only partially vulcanized before the needling, and fully vulcanized afterwards.

Abstract: 869,526. Punching. ALMATIC A.G. April 15, 1958 [April 30, 1957], No. 11919/58. Class 83 (4). In a punching machine, the pressure exerted by the hold-down on the work is dependent on the velocity of the punch. The machine is for punching articles such as pawls or gears, which during punching are held to prevent flow by the hold-down 11 and by counter-pressure exerted by an ejector 30. During the punching stroke liquid is forced by a pump 3 to lower a piston 10 carrying the punch 12. An annular piston 14 within the piston 10 forces the holddown 11 against the work due to the pressure built up in a chamber 13. Liquid from this chamber is drained through a throttle 20 into a tank 23 backed by pneumatic pressure and into cylinder 28 to exert pressure on the ejector 30. After the blank has been punched the pump is reversed and springs 6 return the piston 10, the ejector 30 and the hold-down. 11 being operated from the pressure in cylinder 28 and chamber 13, respectively, resulting from the pneumatic back pressure in the tank 23.
