Abstract: Provided are a roll, a film forming apparatus, and a film forming method. The present invention provides a roll used in an apparatus which may transfer a substrate, e.g., a flexible substrate such as a plastic film and a fibrous or metallic web or film and may form a film on a surface of the substrate, a film forming apparatus including the roll, and a film forming method using the film forming apparatus.

Abstract: A device for controlling web tension is disclosed. The device includes a carriage in which a first guide roller is spaced from a second guide roller by a frame. The carriage or frame pivots about a pivot location. A moving web is threaded through the carriage in a serpentine path. Rotation of the carriage or frame causes web displacement. When tension disturbances occur in the moving web, the device rotates for accumulating or releasing the web material and thereby dampening tension variations downstream. The pivot dancer device can be placed in a communication with a controller for open loop control or closed loop feedback control.

Abstract: A web centering and spreading processing system and related method are used to center a moving web and then spread the web in order to remove wrinkles from the web. The centering mechanism, in one example, has a centering roller that receives the wrinkles web. The outer edges of the web, which tend to be uneven and not centered, are detected and a signal is sent to the centering roller to move the web laterally and thereby center the web. The centered web, which is substantially centered but not necessarily precisely centered, moves to a spreader station that receives the web and spreads it thereby removing any wrinkles in the web. The spreader station may include a roller with a recessed center area and that has at least one set of contoured plates that move across the roller from an inner position to an outer position. The plates have gripping surfaces that grip the edges of the web and spread the web to remove the wrinkles.

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: The invention relates to a method and apparatus for the treatment of continuously moving tubular fabric (1) in the wet state, in which this tubular fabric is deliberately expanded in an expansion zone (3) by blowing air in and the fabric width (WB) effectively obtained is measured. The actual value obtained for the fabric width is compared with a predetermined theoretical value and in the event that they differ a correction value is formed and the quantity of air blown into the tubular fabric is controlled as a function of this correction value. The tubular fabric (1) is expanded immediately after wet treatment and is then delivered to the expansion zone free of tension and with a sealing material store. In this way a compact apparatus is achieved which functions simply and reliably.

The spreading station is arranged downstream from the guide station, so that very high web speeds can be realized because the web corrections are executed very gently and without whipping up the correcting pulses.

Abstract: An elongated knit web is flattened and guided by an apparatus having a support frame which extends longitudinally in a plane and which has an upstream and a downstream end. A pivot supports this frame for pivoting about a pivot axis transverse to the plane at the upstream end. A pair of transversely extending and longitudinally spaced spreader rollers are provided on the frame adjacent the upstream end and each has a pair of screwthread formations of opposite hand, these spreader rollers being driven to spread out the web transversely. A pair of transversely extending and longitudinally spaced guide rollers are provided on the frame between the spreader rollers and the downstream end, these guide rollers being freely rotating and having surfaces which are made to adhere to the web to prevent its edges from curling up. A control system pivots the frame about its pivot axis to position the edges of the exiting web.

Abstract: The disclosure is directed to apparatus for processing of tubular knitted fabric, including an internal flat spreader and width-adjustable edge drives, typically used in connection with other processing apparatus, such as calendars, padding equipment, compressive shrinking stations, etc. The apparatus utilizes a pre-loaded, resiliently biased spreader frame which, within its operating limits, presses outwardly against adjustably movable, opposed edge drive rolls. The spreader frame, which is positioned internally of the moving fabric tube during processing operations, is capable of in-process width adjustments, without either stopping the processing line or damaging the fabric. Width adjustment of the internal spreader frame may be accomplished from a remote operator station. Moreover, the apparatus may incorporate edge-sensing means operative automatically to adjust the width of the spreader to maintain uniformity of width in the processed fabric.

Abstract: Apparatus for opening a textile gathered in rope form includes a spreading device and a centering device, downstream of the spreading device, including two cylinders, maintained with their axes parallel but pivotable in a common plane parallel to the general, desired direction of advance of the textile, between two extreme positions inclined on opposite sides of the said direction. The pivoting of the cylinders is controlled through a sensor which senses a displacement of the textile from the desired direction and acts to return the textile to this direction. If the recall action of the cylinders in either extreme position is insufficient, a respective control device is activated which pivots a spreading cylinder of the spreading device out of its normal working position, in which it is parallel to the other spreading cylinder, into one of two extreme positions to exert a further recall action on the textile.

The centering device comprises a pair of parallel centering rolls with means to vary their inclination to the direction of movement of the fabric, as needed.

Abstract: The guidance system pulls sheet material along its length from a supply and moves the sheet material across a work table through a sewing machine and the like. The sheet material extends through a loop and is moved from a level displaced from the level of the work surface of the work table about a horizontal guide bar and then onto the work table. An edge detector senses the edge of the sheet material, and the guide bar is pivoted about an upwardly extending axis in response to the drifting of the edge of the sheet material away from the desired predetermined path of movement toward the sewing machine to guide the edge of the material back to its desired path.

Abstract: Apparatus for laterally stretching a web of textile fabric comprising a pair of web-stretching devices disposed at opposite sides of the web, each web-stretching device comprising at least a pair of parallel uncurling fingers and a control roller disposed therebetween. The fingers and the roller engage a selvage of the web to exercise a lateral pulling force thereon, and when a detector detects lateral displacement of the web, the position of the control roller relative to the fingers is changed to change the lateral pulling force on the web so as to correct the lateral displacement. At the same time the position of the detector is changed so as to prevent overshooting and render the sensitivity higher and response quicker. When the width of the web changes, the distance between the two web-stretching devices is changed so as to compensate for the change of the web width.
