Abstract: The invention relates to a stenter for a textile material web with two chain conveyors mounted to be pivotable in a scissor-like manner in the feeding section of the machine. The chains extend in the chain conveyors and have gripping means for grasping the material web edges. The free wings or webs of the pivotable chain conveyors are mounted to be movable on a horizontal support by carrier wheels. At least one carrier wheel is in the form of a driven friction wheel, and a drive motor is directly associated with the carrier wheel.

Abstract: A fabric width control system for a fabric compactor for compacting a moving fabric web. The system includes a vision assembly for measuring the width of the moving fabric web downstream of the fabric compactor. A mechanical spreader is located upstream of the fabric compactor for adjusting the width of the web in response to a control signal from an open loop controller. The controller is connected to the vision assembly and the mechanical spreader for controlling the position of the mechanical spreader in response to a change in the width of the moving fabric web from a pre-set value. In the preferred embodiment, a cloth stabilizer is located downstream of the fabric compactor for maintaining the moving fabric web at a pre-determined position with respect to the vision assembly, thereby further increasing the accuracy of the system.

Abstract: A method and apparatus are provided for maintaining the edge of a moving web on a web handling apparatus at a desired operating path. The operating path of a web edge is monitored with respect to a first desired edge path. The web is secured for movement along an intended path of travel. The web edge is maintained at the first desired edge path. The web edge is monitored with respect to a second desired edge path as it is maintained on the first desired edge path. The web is automatically maintained along the second desired edge path.

Abstract: Stenter apparatus for stretching a web to produce a relatively thin film comprises two transversely spaced endless chains one the mirror image of the other relative to the stenter center line (C--C), each chain comprising an inner feed run (9) and an outer return run (10) mounted on supports. Each endless chain is constituted by film clip holders (3) and the chain pases around end sprockets (11B, 12B). The present invention provides a means for lateral adjustment of the feed runs (9) comprising adjustment means for lateral movement of the feed run support relative to the return run support and pivoting portions (10A, 10B) in the outer run support adjacent the end sprockets (11B, 12B) to enable said lateral movement of the feed run. Consequently a major portion of the outer run support does not require to have lateral movement and can be fixed in position and this provides economies in the construction. Further, end sprockets (11B, 12B) of smaller diameter can be used.

Abstract: An apparatus for a tenter frame feeds a fabric web to the nip region of vertical pins and cooperating rollers of a pair of endless belt assemblies which transport the web through a drying chamber. The apparatus includes a guide member which guides the web into the nip at a relatively steep angle, preferably in the range of +.degree. to 60.degree.. The guide member can be supported on a pair of swivel supports, each of the swivel supports being movably supported on one of the endless belt assemblies. Additionally the guide member can be a roller rotatable about its axial length which can be rotated in synchronization with the feed of the web.

Abstract: The disclosure is directed to improvements in tenter frames which typically function to move fabric through a fabric processing step which might be fabric curing or drying. The tenter frame contemplated herein includes various adjustable devices for optimizing the position of the fabric as it is being moved to thereby minimize or eliminate any distortions in the fabric construction which can occur in open-type knits, such as pattern distortions and the like. In addition, the apparatus utilizes a series of mechanical variable speed drives and controllers which are all synchronized with an electric driver motor to better control the operation of a tenter frame as it moves fabric through a processing step.

Abstract: A tenter entry feed assembly and method is disclosed for a tenter which includes a pair of spaced entry feed assemblies (A, 25, 27). Each entry feed assembly includes a parallel pinning rail section (B), an adjacent elongated fabric conveyor (C, 40), and an elongated contoured feedplate (55) adjacent to each conveyor. Also carried by each entry feed assembly is a sprocket wheel (46) at least one of which is keyed for rotation with a shaft (48). The fabric conveyors (C) and contoured feed plates (55) extend next to a main feed roll (54) of the entry system. In this manner, a pinning point (29) is defined which is very close to the main feed roll and the distance between the feed roll and the pinning point is substantially reduced so that control over the fabric may be had positively by conveyor (40) in the zone. Pinning of the selvages of the fabric (F) occurs in a natural relaxed state generally without tension. An output (88) of shaft (48) is connected to a phase adjusting drive ( 94).

Abstract: Apparatus for actuating a sidemovement correcting member of a machine for correcting the sidemovement of a travelling sheet-like article, comprising a linear motor having a scale of a predetermined length and a slider disposed at the bottom of the scale, a casing secured to the outer surface of the slider and put on the slider and the sale for preventing the slider from falling off, and a mounting member for the sidemovement correcting member disposed at the center of the top of the casing.The apparatus is arranged so that the linear motor is moved or stopped at a predetermined position in quick response to a selvedge detector signal and the like, thus assuring a highly accurate positioning control of the sidemovement correcting member.

Abstract: The present application discloses a tenter arm swinging apparatus in which the swing of a tenter arm is performed by rotating a nut threadedly connected to a fixed screw shaft, and arm swinging means is housed in a case housing said nut.According to the present invention, the whole apparatus may be constructed in a very compact structure and installed readily and conveniently, regardless of the spatial conditions outside the apparatus.

Abstract: A continuous padding type dyeing machine particularly suitable for handling elastic fabrics, the machine including a padding bath with at least a pair of main and auxiliary padding rollers and a dryer having a pair of spaced endless conveyors means provided on opposite sides of a path of travel of the fabrics for transferring them through the dryer without causing excessive tensioning thereto. The endless conveyors are movable in and along a number of adjustable guide members and provided with a number of pin members for holding longitudinal side edge portions of the fabrics. A pair of detectors are provided at a lower end of a vertical section of the path of travel of the fabric through the dryer in association with opposite longitudinal side edges of the fabric for adapting the guide members to the particular width of the fabric under treatment.
