Problems solved by technology

If such a device is not used, as a last resort, the sheets can be threaded on the ring by hand, but this is difficult and results in irregular perforations, making the sheets prone to tearing, and the excess paper folded in the between adjacent sheets so that the sheets do not stack flat together

Embodiment Construction

[0012] The pressing and perforating device is assembled on the ring frame of the lever arch ring folder, and compresses the sheets mounted on the ring frame. Perforating devices, although known in the prior art, have not heretofore been combined with hold-down devices, and perforating devices can be produced in a simple and cheap manner without the need for conventional punching devices before the documents are loaded into the folder. A hole machine pre-punches holes in a sheet of paper. In addition, punched files can be aligned with the folder itself or with files already in the folder to ensure the punched holes are in the correct place.

[0013] FIG. 1 shows a conventional lever arch folder with a compression and perforation device 16 according to the invention mounted on the ring frame 2 of the folder. The pressing and perforating device shown here has a longitudinal button arrangement; however a different arrangement, such as a transverse button arrangement as described ...

Abstract

A pressing and punching device for includes a base with a pair of holes, through which a ring frame of the file (for example lever arch ring file) can be fixed. The holding ring frame can be selectively released in the use, so that the documents can be pressed and held in the file. A handle component can be hinged to the base, can be moved between the open and the close positions. The said base and handle are provided with teeth and holes respectively. The teeth and holes are metal for punching holes on documents.

Description

technical field [0001] This invention relates to compression devices for lever arched file folders, and more particularly, the present invention relates to compression devices incorporating a perforator for punching holes in the paper. Background technique [0002] Compression devices for securing documents in folders are known. One of the structures has a base with a pair of holes through which the ring frame of the file folder protrudes, and a pair of elastic rods are held on the base and extend between the pair of holes, the base The seat is elongate and the holes are separated by a certain distance in the general longitudinal direction; an arm, which includes a part for bending the rod at a position between the two holes, said arm can bend the rod at the bending part Movement between a first position and a second position in which the bending member does not bend the rod or slightly bends: and two sets of lugs, each mounted on a base between the ...
