Abstract:
The rotary anvils herein may be used in combination with a tool member to perform various types of manufacturing operations, such as cutting, bonding, and embossing. The anvil roll (100) includes a cylindrically-shaped outer circumferential surface (102) and is adapted to rotate about a first axis of rotation (104). More particularly, the anvil roll (100) includes a body (110) formed from a first material (118), such as a metallic material. The body also includes grooves (130) in the outer circumferential surface (102), and abrasion resistant material (120) is fused to the body to fill the grooves (130) to form strips (112). During operation, a tool member (134) is positioned to contact the strips (112) of abrasion resistant material (120).
Abstract:
The invention relates to a tenter frame for treating web materials such as woven or knitted farbics, film, or the like, to an 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 (30) having a plurality of pins (34) thereon engage opposite edges of the web material (26) for holding it as it is treated on the tenter frame. Pinned rolls (36) 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 (60) is also 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 (36), after which trimmed edges are automatically removed from the pins (38) for discarding.
Abstract:
Aspects of the present disclosure involve methods and apparatuses for cutting and removing trim from an advancing substrate. Particular embodiments of the apparatuses and methods disclosed herein provide for removal of continuous lengths of trim, and in some embodiments, discrete pieces of trim from an advancing substrate.
Abstract:
A device for removing stray fibers from a shade fabric includes a fabric teaser adapted to loosen fibers along an edge of the fabric and fiber cutters adapted to remove stray fibers from the shade fabric. The fabric teaser comprises first and second rotary brushes each having a brush element. The brush elements of the first and second rotary brushes are adapted to receive the edge of the shade fabric between the brush elements and to rotate in opposite rotational directions for loosening the stray fibers along the edge of the shade fabric. According to one embodiment, the fiber cutters include reciprocating cutting elements and the fabric teaser includes rotary brushes having radially-extending bristles arranged to receive the shade fabric between the bristles. The device may include a mounting bracket for adjustably mounting the fabric teaser and fiber cutters on an elongated rail.
Abstract:
Device for compacting and discharging weft tail-end waste of weaving looms, in a system for removal of said waste comprising a pneumatic conveying duct (1) connected at one end to an inlet mouth (2) for the weft tail-ends and at the other end to a storage container. A portion of the conveying duct (1) provided with an output filter for the conveying air comprises a motor-driven screw element (7) for entangling said weft tail-ends. An outlet aperture of said portion of the conveying duct may be closed by valve means (9, 10, 11) for regulating the expulsion of the entangled and compacted weft tail-ends into said storage container.
Abstract:
To improve a device for the lateral sensing of nappless regions on textile webs, especially sponge cloth, in a textile machine in which the textile web runs over a guide roller in the region of the detection device and the napless regions are detected by photodetectors consisting of transmitters and receivers secured on a frame, whereby the detector beams are directed tangentially to the guide roller and thus toward the textile web at its deviation position so that the distance between the photodetectors is automatically adjusted to the surface, it is proposed that the frame (1) is guided with rollers (2) directly on the surface of the guide roller (3) and the transmitters (7, 8) and receivers (4-6) of the photodetector are arranged on a plate (9) secured on the frame (1) at a distance tangential to the guide roller (3).
Abstract:
In order to provide a device for the lateral scanning of napless areas of fabric webs which operates automatically with great accuracy and reliability even at high web speeds while being of relatively simple construction, it is proposed to cause the fabric web (7) to pass over a guide roller (11) and to cause the napless areas (9, 12) of the fabric web (7) to be scanned by means of photodetectors (2-6) consisting of transmitters and receivers, in which the scanning beams are directed tangentially to the guide roller (11) and thus to the fabric web (7) at its deflection point.
