Paper folding device

Abstract

A paper folding device (1) adapted to be attached to a digit of a hand comprises a rotatable member (5) attached to the body (2) of the device via a rotatable attachment means (7), whereby the rotatable member (5) rotates in relation to the body (2). The rotatable member (5), in use, is rolled along a fold of pulp based material and communicates pressure from the device (1) to the pulp based material to form a creased line.

Description

FIELD OF THE INVENTION[0001]This invention relates to a paper folding device, in particular to a paper folding device for use with folding large sheets of paper in design offices, architects' practices, printing establishments or the like.PROBLEM TO BE SOLVED[0002]The closest prior art known to the applicant is U.S. Pat. No. 5,520,604 which discloses an apparatus. for creasing the folded edges of continuous paper products that incorporates a pair creasing tools. The creasing tools are two cylindrically shaped tools, which are positioned on either side with the folded edge of a continuous paper product with axes parallel to each other and perpendicular to the folded edge.[0003]The disadvantage of the known paper folder apparatus is that the creasing tools are integral to a printing process in which two creasing tools are applied to either side of a folded edge of a continuously conveyed printed product. This apparatus cannot be used within a non-mass production environment where the ...

Benefits of technology

[0015]More preferably, said flexible membrane is a silicone material. This provides a device which can be moulded by a mass production means. The silicon also provides a device with an elastic function, which contracts back to its original shape when placed on the user's digit, therefore gripping the outer surface of the user's digit.

[0016]Preferably, said body is formed from a rigid material which fits over the end portion of said digit. This provides a means of supporting the roller whilst directing a downward pressure on to it, without the body of the device deforming and impeding he rotation of the roller. Furthermore, this configuration also provides the means of protecting the finger from any paper edges, which may cut or slice through relatively soft material.

[0017]More preferably, said rigid material is a plastics and/or metallic material. This provides the means of mass manufacturing the paper folding device easily and cheaply. Furthermore, this configuration will enable the device to be recycled at the end of its useable life.

[0018]Preferably, the outer surface of said

Problems solved by technology

The disadvantage of the known paper folder apparatus is that the creasing tools are integral to a printing process in which two creasing tools are applied to either side of a folded edge of a continuously conveyed printed product.

This apparatus cannot be used within a non-mass production environment where the printed product is typically a single sheet of
