  • Patent number: 5679438
    Abstract: A process of decorating fabric includes the step of imparting wrinkles to the fabric oblique to the warp and weft directions and heat setting the wrinkles into the fabric. The wrinkle imparting step may include moving the fabric longitudinally and simultaneously moving portions of the fabric from side to side by frictionally engaging the fabric to an oscillating means such as an elastomeric pad or interleaved fingers and oscillating the pad or fingers from side to side. Heat setting of the fabric includes exposing the wrinkled fabric to heat at a sufficient temperature and for a sufficient duration to set the wrinkles in the fabric. Desirably, the wrinkled fabric is in contact with a transfer print paper while the fabric passes through the heat setting step to set the wrinkles and fix color on the fabric. The longitudinal movement is desirably coordinated with the side to side movement to obtain aesthetically pleasing results. The invention also includes apparatus and the product.

  • Patent number: 5539964
    Abstract: A container for a strip (12) of light-sensitive material includes an elongated opening for withdrawing the material from the container. Strips (22) of light-locking material are provided on both sides of the opening, the strips being made from a napped and sheared woven fabric (12, 14). The fabric is dyed, dried, napped, sheared and heat set prior to preparation of the strips. A method of producing such a light-locking material is taught which includes steps of passing the woven fabric multiple times through napping and shearing operations to increase the pile density.

  • Patent number: 5483729
    Abstract: A machine for shearing pile fibers from the surface of a textile fabric which is conveyed over the narrow edge of a cloth holder. The cutting is accomplished by a scissors-like action between a stationary cutting blade and a plurality of helical blades which are mounted on a roll which is rotated about a horizontal axis for moving the helical blades into cutting contact of the horizontal cutting edge of the stationary blade. The stationary blade is mounted on a holder which is pivotally mounted on a horizontal axis to enable the stationary blade holder to be pivoted by a drive mechanism to change the relative position of the cutting edge of the stationary blade relative to the cloth holder. The roller for the helical blades is mounted on a rotary blade holder which is supported on the stationary blade holder for movement with the stationary blade holder so that the cutting edges of both the stationary blades and the rotary blades and the helical blades move in unison relative to the cloth holder.

  • Patent number: 5446950
    Abstract: A shearing apparatus of this invention provides a uniform thread shearing, and a high discharging capability for sheared threads. Even when a discharging power is raised by increasing a suction power of a suction box, a cloth having threads subjected to shearing and passing over a shearing table, will not float from the shearing table thereby providing uniform shearing and preventing damage to the cloth. An outer wall having a shutter forming a slit is hinged to the suction box such that it is pivotable with respect to the wall of the suction box so that an angle between the outer wall and the suction box can be adjusted. Inside the suction box, there is provided a rotating blade device comprising a cylinder with a plurality of radially disposed ditches on the surface of the cylinder and longitudinally extending blades fixed substantially equidistantly and parallel each other.

  • Patent number: 5379498
    Abstract: Shearing operations on textile pile fabrics may be repeatably controlled precisely by controlling operating parameters of the shearing machine to maintain constant the average number of times each pile loop of the fabric is cut by the shearing blades of the shearing cylinder, which is accomplished by calculating a numeric value representing cuts per pile loop as a function of the rotational speed of the cylinder, its number of shearing blades, the widthwise dimension of the nose surface of the fabric rest, and the fabric traveling speed, and selectively adjusting one or more of these parameters as necessary to achieve the desired number of cuts per fabric loop.

  • Patent number: 4882818
    Abstract: A carpet shearing machine for modular carpet which includes a moveable table which is provided with means for holding the modular carpet. A carpet shear is positioned on a moveable frame which is adjustable to a predetermined distance above the moveable table. The moveable frame may be pivoted and raised above the moveable table such that the modular carpet on the table may be passed beneath and through the shear and thereafter the shear is raised to permit the moveable table to return to its original position.

  • Patent number: 4649606
    Abstract: Apparatus and method to raise the edge fibers of a cut pile carpet tile to ensure that they are cut by the rotating shear which is cutting the rest of the fibers in the tile. The tiles are overfed into the shear so that they abut one another causing the edge fiber, on the edge transverse to the direction of travel of the tiles, to be pushed upwardly. At a position adjacent the shearing member air under pressure is supplied against the traveling edge of the carpet tile to project the edge fibers into the upstanding position.
