Abstract: Method and apparatus for making a nonwoven fabric wherein a first group of filaments are projected in a longitudinal direction into the nip of a pair of nipped and moving collecting surfaces in such a manner that the filaments fold into and are captured and held by the nip with spans of the filaments lying in the plane of the nip and at the same time projecting a second group of filaments in a longitudinal direction toward one of the collecting surfaces at a location spaced from the nip. The second group of filaments impinges on an impact plate positioned above the collecting surface and is pulled off the impact plate by the moving collecting surface, this causing the filaments in the second group to extend primarily in the machine direction. The moving collecting surfaces carry the groups of filaments into contact with each other to form a nonwoven fabric which is subsequently bonded in a conventional manner to form a finished fabric.

Abstract: Self-curing elastomeric compounds in liquid suspension are sprayed onto a warmed rotating former having preferably a form developed from the radial dimensions of the inner tube to be made. The tube is cured and complete on the form by transposing one end of the sleeve to the opposite axial end of the former where the one end is seamed to the other end of the sleeve. Both the process and the tube produced by the process have advantages in manufacturing cost, in material saving, and at least equal quality performance relative to conventional inner tubes and methods of making them.

Abstract: A method and mechanism for preparing individual reclosable thin plastic bags with rib and groove profiles delivered in unengaged position on the finished bag, whereby said bags are made from a continuous supply of layers of film having critically shaped small rib and groove profiles on facing surfaces thereof interlocked with each other and continuously advancing the layers of film and inserting a fixed separating finger between the rib and groove profiles so as to draw them apart, maintaining the profiles in alignment by grooves which do not press the profiles flat but carefully guide them laterally, guiding the film profile layers toward each other and then immediately pressing the profile layers together with a sealing and cutting means following the finger, so that the profiles are interlocked at the location of sealing only.

Abstract: Apparatus for uniting exposed photographic roll films into a continuous web which is already for transport through a developing machine has a housing which is lightproof and has two inlets, one for admission of cassettes which contains exposed films and the other for reception of exposed films. Successive cassettes which are introduced through the first inlet are conveyed into the range of a film removing mechanism which automatically removes the films, without breaking the respective cassettes, and the removed films are transported to a splicing device. If the position of roll film in a cassette is such that the film cannot be expelled by the removing mechanism in the housing, the cassette is opened in a darkroom and the film which is removed from the opened cassette is introduced though the second inlet.

Abstract: The machine is for aiding in attaching stiffening elements or stays to shirt collars or to inserts which are later attached or positioned inside the outer surface of the collar. The stays are first stamped from sheets of hard thin flexible material such as a polyester plastic and coated on at least one side with a film of heat sensitive adhesive. The stays are stacked in a magazine with the side containing the adhesive facing either upwardly or downwardly depending on which of the collar elements the stay is to be attached to. Each end of the collar, or liner, is tautly drawn over a thin shelf of the same configuration as the outline of the collar. A machine element will move the lower most stay from beneath the stack and position it within a channel to be engaged by another machine element and moved into position within the collar or liner where it is to be attached.

The apparatus is made up of a generally U-shaped frame having legs supporting two spaced pipe clamps. The frame supports a fitting holder on a springloaded rod by which a controlled force can be applied on the fitting while fusing the fitting to the pipe. The fitting can also be moved toward and away from the pipe in order to insert and remove a heating mechanism to melt the plastic.

Abstract: A process for lining an air-permeable container, such as a paper cup, with a thermoplastic foil by directing a warm pressurized stream of gas to press the foil into place and varying either the flow rate or temperature of the gas stream or both to guarantee the foil shape within the container while it is thus controllably cooled and solidified. The apparatus includes a controllable discharge valve, such as a relief valve formed at the edge of a spring loaded cover through which gas is supplied, for allowing a faster gas flow for cooling than used for deep drawing the foil. Either one or two gas supplies may be used. In the case of two, the gas supply for cooling is at a higher pressure than that used for deep drawing and is preferably at a lower temperature.
