Folding apparatus

A folder apparatus is disclosed which is adapted for use with at least two adjacently arriving webs and having at least one fan wheel. The fan wheel is provided with a number of compartments delimited by guide disks to ensure, that in the case of different processing of the two or more webs, that all of the compartments therefor are used. The fan wheel of the folding apparatus is divided up into a number of laterally adjoining fan wheel sections, which number corresponds to the number of webs to be handled and able to be driven separately from each other by associated drive means.

Folder apparatus

In the case of a folder with at least two folding cylinders having cooperating folding members in the form of folding blades and folding jaws and intended for processing products of very different thickness, more reliable operation may be achieved if at least one folding cylinder has circumferential sections which are able to be adjusted in the radial direction.

Folder

A folder, and more particularly an adjustable folder for web feed gravure presses, comprising a collect cylinder able to be set for collect runs and non-collect runs and provided with holding elements (preferably in the form of grippers) and tucking blades having actuating elements preferably in the form of follower rollers which are operated by a respective cam, whose active cam part, which is preferably in the form of a recess, is adapted to be selectively exposed and covered over by means of a covering means, which is coaxial to the cam and is provided with drive cam elements which are mounted on cam element carriers coaxial to the cam and are able to be driven. In order to achieve a high degree of adaptability as regards different types of collect operations the covering cam elements of the covering device are mounted on the cam element carrier in such a manner that they may be radially adjusted.

Sheet-like products coming off a folder are firstly transported some distance before being caused to overlap. In order to slow down the products to cause this to take place and to arrange them in a perfectly regular feed stream without being damaged, the products are engaged by grippers that are moved along a preferably arcuate path on a support in the course of which the products are slowed down by the grippers to the speed of a delivery belt on which the products are then deposited.

Method and apparatus for the stream feeding delivery of sheet products

In a staple wire supply system for use in connection with printing machinery or the like and of the sort having a fixed wire guide pipe past whose outlet end a knife is moved for cutting the wire down to the size needed for stapling, the time needed for the operation of changing over to a new reel of wire when one reel has run out may be greatly cut down by so designing the system that two reels may be supported thereon at a time and having a unit for running one wire from one such reel to the guide pipe and guiding the other wire into a ready or waiting position. Between this unit and the guide pipe there are two wire driving parts, such as pinch rollers acting on opposite sides of a capstan, which may be changed over in direction and may be used for moving wire from the two reels in oposite directions at the time of reel changing.

System for the supply of staple wire to a stapler

A switch system for clearing spoiled items from an overlapped stream of paper products such as signatures has a three-flight conveyor belt transporting system whose middle flight may be rocked bodily so that its downstream belt support roll, functioning as a switch roll, is moved between an upper position in which it is leveled up with the next flight, and a lowered position for sending the stream, when made up of spoiled items, downwards under the next flight to a separate delivery. The side face of the upstream belt roll of this same next flight is covered by a cover for neatly separating the stream and switching it over into the downward parts under this next flight. Over the switch a backer roll is placed so as to have its weight supported on the stream of products (in turn supported by the switch roll). In this way the products are well gripped and controlled.

A stapling machine is provided of the type which includes at least one stapling cylinder having a wire transport, a shaped disk which for the formation of the staples bites into a peripheral recess provided in the stapling cylinder, and a fixed staple guide which, with reference to the rotational direction of the stapling cylinder, is positioned after the shaped disk, projects into the peripheral recess and is underrun by the finished staple. The stapling machine is characterized in that the staple guide has, in the area of its surface which is underrun by the back of the staple, a post-bending edge which bites deeper into the recess in the stapling cylinder than does the outer periphery of the shaped disk.
