Abstract: Two methods for redirecting a continuous paper web with a face up orientation from a first direction to a second direction with either a face up orientation or an opposing face down orientation are provided. The directions correspond to paper processing devices such as printers and cutters, and an assembly to do the same is also provided. In the preferred embodiment of the assembly, the web passes about a turnbar that is moveable between a first and a second position. In the first position, the web is redirected face down along a second direction. In the second position, the web passes about a roller perpendicular to the second direction and is redirected along the second direction in a face up orientation.

Abstract: Bowed spreader apparatus for laterally stretching, or stressing, a web of material carried in a selected direction along a conveyor path includes an elongate stationary spreader bar extending laterally of the path. The spreader bar has a web support face which is convexly curved both about the longitudinal axis of the bar and along the longitudinal axis. The bar includes a formed elongate support body having a degree of flexibility allowing the body to be bent in a bowed configuration. A face surface of the body is formed in a convex curve about the longitudinal axis of the body and a plurality of hardened elements are individually secured to and cover the face surface of the support body. An underlying interchangeable profiling support having a convexly curved upper surface forms the spreader bar into a selected bowed configuration.

A pivot bearing in the form of an antifriction bearing is cut as a segment so that the material web can run close to the swivel axis.

Abstract: A roll quadrant conveyor for conveying strip material generally includes a plurality of support members for supporting a plurality of rolls around a quadrant roll of any desired wrapping angle and, further, a plurality of rolls journaled for rotation in the support members. The rolls are positioned on opposed sides of a conveyor centerline, with each roll positioned at an angle of less than 90° with the conveyor centerline. The rolls define a chevron pattern around the wrapping angle. The strip material, in motion, is centered on the conveyor by the rolls arranged in the chevron pattern. The rolls are profiled rolls.

Abstract: The problem to be solved by this invention is a conventional printing web position adjusting apparatus poses a problem in which angularly displacing means having excellent accuracy is difficult to install, large power is needed, fabrication cost is high, an adjustment result cannot be detected since a side edge position is detected on an inlet side of the apparatus and space saving cannot be achieved. A printing web position adjusting apparatus for adjusting a side edge position of printing web to a previously,determined position based on an output signal of an edge sensor provided on a downstream side of the apparatus by angularly displacing integrally two of guide bars provided between two guide rollers orthogonal to a travelling direction of printing web and in parallel with each other and respectively having different angular displacement centers arranged such that printing web is made to wrap over substantially 180 degree of peripheral faces thereof while maintaining parallelism therebetween.

Abstract: The present invention is directed to an angle-bar arrangement for deflecting material webs on an angle-bar jacket (1) which is provided with a plurality of air outlet openings (2). Closing elements (6), which seal off respective air outlet openings (2), are movably accommodated in the angle-bar jacket (1). Compressed air enters into the hollow space bounded by the movably accommodated closing elements (6). The movable closing elements (6), whose outer contour (7) corresponds to the inner wall (3) of the angle-bar jacket (1), are driven independently of one another by actuators (18, 20).

Abstract: A system for merging multiple streams of documents in side-by-side relation, such as cut from a paper web, into a single document stream is provided. Each document of a document stream passes over a turnbar driven that inverts and redirects the document, a primary conveyor carries the documents in side-by-side relation toward the turnbars, and a cross conveyor carries the documents away in a single merged document stream. The cross conveyor is angled with respect to the primary conveyor, and the turnbars are angled with respect to each conveyor. The turnbars may be staggered and adjusted to output the documents in any order, and the invention may handle two, three, or more simultaneous document streams. The turnbars may be driven by a single drive means which may be reversible, and may be repositioned to direct documents in either direction the cross conveyor may operate.

Abstract: Method and apparatus for guiding a paper or board web in a paper manufacturing machine, a board manufacturing machine, or finishing units in connection with such machines. Web travel is guided by changing the travel position of at least one wire travelling in contact with the web such that the velocity vector of the wire at least at the point of contact of the web and the wire is directed sideways from the travel direction of the web center line when the web is brought onto the wire.

Abstract: An apparatus for transporting continuous elongate material webs is provided including structure for transporting a material web at a constant speed along a transport path and at least two material web guides arranged along the transport path, at least one guide being arranged upstream and at least one guide being arranged downstream of an intermediate position along the transport path. The upstream and downstream guides are moved relative to each other so as to impart a sinusoidal variation in speed to the material web at the intermediate position.

Abstract: A tension determining apparatus that is arranged above cylindrical air chambers determines tensions at both edges of a web before the web enters helical routes of the cylindrical air chambers. Middle direction changing air chambers among three direction changing air chambers arranged in a row are inclined by a predetermined angle according to the difference between the tensions at both edges of the web. Therefore, a snaking and a bias of the web are reduced, and the web can run stably.

Abstract: A paper feeding device has a first guide portion through which paper having a preselected width and thickness is introduced, a second guide portion for receiving the paper introduced into the first guide portion, and at least one connecting guide portion disposed between the first and second guide portions.

The clamping portion of the paper feeding roller mechanism is disposed generally parallel to the connecting guide portion of the paper feeding guide.

Abstract: A novel method and apparatus to apply a corrosion protection in the form of a zinc (or other sacrificial anodic material) tape to a tubular member such as pipe or coiled tubing to used as an underground or underwater pipeline or flow line is disclosed. The zinc tape is applied with sufficient heat and pressure to form a metallurgical bond between the zinc tape and underlying metal pipe. This allows the zinc tape to act simultaneously as a continuous protective metal barrier to the normal scrapes and nicks the pipe experiences during installation and as a sacrificial anode. The novel apparatus preheats the zinc tape with a nozzle containing heated gas such as nitrogen as it approaches the pipe surface. At the point of contact with the pipe surface, the nozzle continues heating the tape and pipe surface while a plurality of pressure rollers exert sufficient force on the zinc tape to form a metallurgical bond between the zinc tape and the pipe surface.
