Description

[Detailed description of the invention] Improvement of comb binder l'arm color and friend The invention features a series of equally spaced pinding holes adjacent to one edge. - a comb bar used to bind (for example) stacks of paper sheets; Concerning improvement of indah.

A typical comb for a binder consists of multiple combs spaced longitudinally that are bound together. Including fingers. Each finger extends in a plane extending generally perpendicular to the longitudinal axis. A brushed or arched arrangement is or can be adopted, which makes the fingers less heavy. When placed through the binding holes in the sheet, the fingers The side edges of the stack can be bound or stapled, and thus - the stack of paper sheets can be used as a book. and open it.

One common comb binder is made of plastic material and includes a spine. This back The fingers extend from ing.

Then, in the binding operation, the fingers are extended - stacking sheets into the binding hole of the coil, then release the coil and stitch around the edges of the overlap. .

Other types of conventional comb binders are made from wire-like materials and are based on Contains lines. From this baseline the fingers extend into a generally hook shape.

The comb binder initially has an opening formed between each finger and the baseline. It is shaped like this. This inserts the finger into the binding hole.

The fingers are then irreversibly deformed to bind the opening and pass through the holes to form a sheet. - The edges of the stack can be wrapped around, allowing the paper sheet to open as a book. can. One such comb binder is described in British Patent No. 1460444. has been done.

Although plastic combs of the type described in the two previous columns are widely used, Non-recoverably deformable combs such as those described in This makes it possible to open pages with a large degree of freedom, especially when the page opening is restricted to approximately 3106. It has the advantage of being able to open approximately 360" compared to other plastic combs. do. The invention also relates to such a comb, in particular a bridle at the front end of the hook. Parallel sections of wire connected to each other by ridges form a hook section. Regarding eel comb.

For ease of nomenclature, such irreversibly deformable combs will hereafter be referred to as white. I'll call it Yakoum.

Note that although wire is the most commonly used material, the term "wire" is not a generic term. The term "wire" was used to describe the production of this type of comb. It should be understood that it also includes other materials that can be used to

One of the problems experienced with wire combs is the binding of fingers - overlapping sheets. and provide a support device to facilitate this task. This is one of the objects of the present invention.

According to the invention, a plurality of supports extend from the support surface in a spaced arrangement with the support surface. A wire comb support device is provided that includes a member. Each of the support members is also The loop portion of the comb formed between adjacent fingers of the comb is engaged and This allows the comb to be supported from the support device in a cantilevered manner.

The comb is thus provided with a prominent and upwardly projecting finger on one side of the device. This allows the finger to be inserted into the binding hole. A single layer of sheets can be mounted on the fingers, and the fingers are deformed to Preparations are made for mutual fixation.

Preferably, the supporting surface is inclined with respect to the vertical plane, in particular between 50° and 70°. An angle of 60° is preferred, in particular an angle of 60°, so that the row of openings points generally upwards. ing.

Preferably, each support member includes an upper portion formed at a slight distance from the support surface. Preferably, a seat surface is also provided, and the base portion of the comb is sealed onto said seat surface. It is convenient to allow contact between the two.

It is preferable that the spacing of the upper parts is even, and that the upper parts have similar spacing. The combs may be arranged in groups with different comb sizes, but the basic Combs based on multiples of size can be mounted on this support device.

Therefore, if the finger spacing is 16.9mm center spacing, then 8.45mm A small comb with fingers spaced on centers can also be fitted, with every other comb having fingers on centers of Nga will not be supported.

As an alternative, a comb with 33.8 mm based fingers may be attached to the device. It is also possible to attach the comb, in which case a pair of adjacent fingers of the comb have two It will be supported by a support device.

A supporting device clamps the stacked sheets by means of which the comb is deformed by a machine, and this forming a part of said machine for forming a stack of sheets into a bound form; is preferred.

Herein, preferred embodiments of the invention are selected for the purpose of illustrating the invention by way of example. The supporting device will be explained in detail with reference to the accompanying drawings.

In the attached drawings, Figure 1 is a perspective view of a normal wire comb, and Figure 2 shows a wire comb attached on top of it. FIG. 2 is a perspective view showing a preferred embodiment, Figure 3 - Longitudinal section of Figure 2 showing the use of a comb to bind stacks of paper sheets. It is a front view.

- used to support the frame 6, while - for the pindings spaced in rows; The overlapping paper sheets 8 with holes 10 are bound by the comb during the binding operation. It is attached to the comb before it is removed. The support device also includes a housing 12; Housing 12 typically forms part of a bookbinding machine. Inclined surface 1 of housing 12 4 is equipped with a support plate 16, which allows the device to be placed in its normal position on a horizontal surface. In this case, the support plate extends at an angle of approximately 60° to the vertical plane.
