Abstract

In an apparatus for producing wire comb bindings for stationary articles and printed products, the wire comb 3 formed in the wire comb forming device 1 is conveyed to a wire comb reshaping device 4 which reshapes the wire comb 3 to a wire comb binding 5. As a consequence of the intermittent emergence of the wire comb 3 from the wire comb forming device 1, the wire comb undergoes vibrations which must be eliminated before the entry of the wire comb 3 into the wire comb reshaping device 4. To this end, a toothed wheel 7, mounted to be freely rotatable, is arranged in the conveying region of the wire comb 3 between the wire comb forming and wire comb reshaping devices 1; 4, engaging into the wire comb 3 and damping the vibrations thereof because of its moment of inertia. <IMAGE>

Description

Stw .; Wire comb promote - dampen vibrations

Device for producing wire comb bindings for paper and Printed products The invention relates to a device for producing wire comb bindings for paper and print products.

Such a device consists essentially of a wire comb forming device as described in DE-GZ 8133321.6 and from one in US-PS 4,047,544 Wire comb deforming device described.

In the wire comb forming device, the wire fed to it becomes continuous alternately bent into a hairpin shape and thus formed into a so-called wire comb.

The continuous wire comb thus formed then becomes the Urahtkammverformeinrichtung supplied, in which it is deformed into a C-shape.

Since the wire comb from the wire comb forming device intermittently exits, it is made to vibrate.

To ensure that the wire-comb forming device works properly however, it is necessary to calm the vibrating wire comb before entering it, that is, to dampen its vibrations.

It is known for this purpose between the wire comb former and to provide a so-called loop memory for the wire comb forming device, in which the wire comb is temporarily stored in a loop, the wire comb largely reassured.

The disadvantage here, however, is the relatively large space requirement for the loop memory, which is the constant endeavor to keep lengths as short as possible of machines and devices in no way.

Stw .: Wire comb promote-dampen vibration-5 The invention is therefore the task is to eliminate the vibrations of the wire comb in its direct conveyance from the wire comb forming device to the wire comb forming device to reach.

According to the invention this is achieved in that in the area of the conveying path of the wire comb between the wire comb forming device and the wire comb forming device a freely rotatably mounted gear wheel engaging in the Urahtkamm is arranged.

According to the invention is also between the wire comb forming device and the wire comb deforming device has a wire comb leading and opposite to it Exit plane from the wire comb forming device twisted by 90 degrees Guide plate provided.

Another feature of the invention is that the gear is arranged in the area of the horizontal section of the guide plate.

The vibrations of the wire comb caused by its intermittent Exit from the wire comb forming device are generated by the arrangement of the freely rotatable gear wheel engaging in the wire comb due to its moment of inertia successfully steamed.

Complex and space-consuming loop memories can thus be avoided and a direct conveying path between the wire comb forming device and the wire comb forming device getting produced.

The invention is to be described in more detail below using an exemplary embodiment explained.

In the drawing is a device for producing braht comb bindings shown in a simplified manner.

Stw .: Wire comb promote-dampen vibrations-D One not closer here Urahtkammformeinrichtung 1 to be described (see DE-GM 8133321.8) is a wire 2 supplied, which by continuous alternating hairpin-shaped seals to one Wire comb 3 is formed.

This wire comb 3 will not be described in detail here Wire comb deforming device 4 (see US-PS 4,047,544) supplied, in which he transversely is deformed in a c-shape to its longitudinal axis to form a wire comb binding 5.

To guide the wire comb 3 is between the wire comb forming device 1 and the wire-comb forming device 4 a twisted guide plate 6 is provided.

Through this guide plate 6, the wire comb 3 is before entering the wire comb deforming device 4 by 90 degrees with respect to its exit plane twisted out of the wire comb forming device 1 so that it is the wire comb forming device 4 is fed in the correct position for the deformation process.

As a result of its intermittent exit from the wire comb former 1, the wire comb 3 is set in vibrations in the direction of its longitudinal axis works.

However, in order to ensure that the wire comb 3 To ensure in the wire-comb deforming device 4, it is necessary to use the vibrating Wire comb 3 to be calmed beforehand, that is, to eliminate its vibrations.

For this purpose, in front of the wire-comb deformation device 4 in the dereich of the horizontal Section of the guide plate 6, a gear 7 is arranged.

The gear 7 is freely rotatable and engages in the wire comb 3, which turns it into rotation.

Due to the moment of inertia of the gear 7, the vibrations the Urahtkammes 3 largely eliminated because the peripheral speed of the Gear it 7 the Stw .: feed wire comb-5 dampen vibration-II medium speed of the Urahtkammes 3 sets.

Thus, the wire comb 3 moves almost after passing the gear 7 steadily.
