Abstract: A roll device as a spreader roll has a rotating hollow roll tube which at the ends thereof is rotatably mounted by means of bearing ends which are mounted in rotary bearings. The roll device has a tension element which runs so as to be eccentric to the central longitudinal axis of the roll tube through the roll tube and by internal tension toward the ends of the roll tube is impinged by a force with pressure. As a result, the roll tube is capable of being bent by way of an impingement of the tension element with a force, the deflection being transversely away from the longitudinal extent of said roll tube, if the tension element is tensioned in relation to the roll tube in an axial direction.
Abstract: A method and apparatus for automatically unravelling a fringe area in a fabric is provided. The apparatus uses a reciprocating, hooked needle and a reciprocating blade to pull weft threads from the plane of a fabric and cut them off. The needle and hook are advanced in the direction of the warp threads, unravelling the weft threads until a fringe area of a certain width has been formed. The apparatus is then displaced along the edge of the fabric and the unravelling cycle is repeated. The apparatus continues to be moved along the edge of the fabric until the fringe area extends the length of the edge.
Abstract: The invention relates to a tenter frame for treating web materials such as woven or knitted fabrics, film or the like, to apparatus for removing a web from a tenter while controlling the web and to a process for removal of a web from a tenter. A pair of endless opposed tenter chains having a plurality of pins thereon engage opposite edges of the web material for holding it as it is treated on the tenter frame. Pinned rolls are provided for engaging and transferring the web material from the pins of the tenter frame with the web taken off of the tenter chains without loss of control over the web. A cutter unit is also be provided for trimming the edges from the web after it has been removed from the tenter chain, and while the web remains under control of the pinned rolls, after which trimmed edges are automatically removed from the pins for discarding.

Abstract: This invention relates to a fabric having a radiation cured crosslinked coating composition applied to the selvages of the fabric to provide ravel resistance thereto. The coating composition is a copolymer of an elastomeric-forming low viscosity monofunctional acrylate monomer and a reactive polyfunctional acrylate monomer. A method of forming a ravel resistant selvage in a fabric is also provided.
Abstract: A process for forming crepe fabrics on a shuttleless loom is provided which includes temporary stabilization of highly twisted (e.g., 40-70 TPI) filament yarn. To this end, hot melt size is applied at a predetermined temperature in predetermined amounts (e.g., add-on of about 10.5-13.5%) immediately after twisting so as to reduce the liveliness of the yarn and to thereby permit it to be woven. After weaving, the yarn stabilization is reversed by a desizing operation. The fabric is subsequently heat treated to develop crepe characteristics.
Abstract: Disclosed is a remotely-controlled adjustable-curvature roll of the present invention which includes a hollow, cylindrical axle in which two rods are inserted. Each of the rods is securely fastened to an endplate at one end of the axle, and the opposite end of each rod is threaded within one of two oppositely rotating intermeshed gears. An air-impact motor is connected to one of the meshed gears to rotate the gear to which it is connected. The rotation of the gears in one direction causes an increase in the compression applied to one of the rods while at the same time exerting an increased tension on the other rod which is connected to the oppositely rotating gear. This combination of tension and compression causes the curvature of the roll to change. A remote control unit regulates the flow of air from an air supply to the air-impact motor. The remote control unit includes a filter for filtering the air supply and an oil mist lubricator for adding a lubricant to the air supply.
Abstract: The adjustable-curvature roll of the present invention includes a hollow, cylindrical axle in which two rods are inserted. Each of these rods is securely fastened to an endplate at one end of the axle, and the opposite end of each rod is threaded within one of two oppositely rotating intermeshed gears. An adjusting hexagon or other similar adjusting device is connected to one of the meshed gears and the turning of the adjusting device in one direction causes an increase in the compression applied to one of the rods while at the same time exerting an increased tension on the other rod which is connected to the oppositely rotating gear. This combination of tension and compression causes the curvature of the roll to change. An indicator attached to the adjusting device provides a reading of the chosen degree of curvature. The axle may be surrounded by an outer sleeve which rotates, through the aid of ball bearings, around the axle.
Abstract: A spreader roll for webs of textile material has a flexible shaft whose end portions rotate in or with pairs of bearings installed in sleeves which are pivotable about horizontal axes to thereby change the curvature of the shaft and/or slidable with respect to stationary holders to thereby effect or change lateral deflection of the shaft. The shaft is surrounded by and fixed to annular supporting elements which are surrounded by an elastic hose whose ends are sealed against entry of atmospheric air.
Abstract: A trimming mechanism for an overedge sewing machine includes an elongated cutter arm driven in oscillatory movement to drive a movable cutting blade which cooperates with a fixed cutting blade to trim material passed through the sewing machine. An improved cutting blade mounting means is provided for simultaneously mounting the movable cutter blade on the driven cutter arm and automatically aligning the movable blade for cooperation with the fixed blade.
Abstract: A press roll for acting in opposition to a counter roll. The press roll has a support member which is supported at its opposite ends. The support member is stationary in certain most embodiments and rotatable in one embodiment. A flexible, liquid-tight endless press jacket is wrapped around the support member. At each lateral end of the press roll, the press jacket is fastened to the outward end of a supporting disk, which is rotatably mounted on the support member. The lateral edge zones of the press jacket are both deformed radially inwardly around the outside of the respective supporting disks and each edge zone is clamped there by a annular clamping flange. To facilitate deformation of the edge zones, at least one of the edge zones terminates in a series of tongues separated by cutouts arrayed around the roll. Coiled tension springs engage the edge zone and/or the tongues to pull them in the direction toward the axis of the roll.
