摘要:
A device is provided which is usable to draw at least one web of material or at least one web strand, that includes several webs of material, into a folding apparatus. The folding apparatus includes at least an upper structure, at least one folding funnel and a cross cutting device for separating the web of material, which has been transported in the upper structure and folded on the folding funnel, into individual products. At least one guide rail is provided. A holding part with a guiding end of at least one web of material fixed thereto, is displaceably guided on a path of web travel of the web through the upper structure. At least one guide rail is provided along the folding funnel.

A paddle wheel is used to deliver folded products to a conveyor belt in a shingled fashion. The paddle wheel has a plurality of pockets which are formed by circumferentially spaced curved paddles. The thickness or width of each product receiving product is adjustable by providing a guide strip in each pocket. The end of the guide strip adjacent the bottom of each pocket can be shifted radially with respect to the axis of rotation of each paddle wheel by actuation of a drive assembly.

A longitudinal folding device includes formers for longitudinally forming and folding paper webs having different widths. Each former, together with its folding rollers, hopper roller and longitudinal cutting device is supported in a frame such that the former can be displaced in the axial directions of both the folding rollers and the hopper roller.
摘要:
An endless web of material, such as a web of paper, is drawn into a device by using moving traction devices along the path of web travel. Web guide rollers that support the web in the device are accelerated before the arrival of the leading end or the beginning of the material web.
摘要:
A paper web is drawn into a printing and can be guided along a selected one of several paths. The paper web is weakened along a line of separation and is then held by a retaining system that can move the web in a conveying direction along a first path. The web is fed to a different conveying path and is separated ot torn along the line of separation. This line of separation or weakening is formed at an angle to the production direction.

A turning bar arrangement for paper webs in a web-fed printing machine provides a compact and space-saving construction. A pair of turning bars are connected to each other while forming an acute angle and are mounted so that they can be displaced in a first plane of the turning device. A second similar arrangement of turning bars is provided in a second plane of the turning device.
摘要:
Guide rollers in a web-fed rotary printing press are cleaned by a web of material that is provided with signal information, such as a bar code or a punch code. The retrievable signal information is used by one or more signal reading devices that are used to apply cleaning agent to the web and to create a speed differential between the guide roller and the material web.
摘要:
A roller or a cylinder of a rotary printing press is cleaned using a liquid. A carriage is movable back and forth along the roller or cylinder. A supply container carries a clean liquid in a specified amount. A dirty liquid is returned to a receptacle. The clean and dirty liquids are supplied to, and removed from, the carriage when it is in a parked position.
摘要:
A device for cleaning a roller in a rotary printing press uses a plurality of rotating brushes. Spray nozzles are arranged centrally in each of these rotating brushes. The brushes are supported on a carriage that can be moved along the length of the roller which is to be cleaned.
