Bending machine, particularly rope bending machine
Description
The present invention relates to a bending machine,
particularly in the form of a rope bending machine, according
to claim 1.
Known bending machines have the problem that, when viewed in
the advance or feed direction of the material to be bent, a
lot of space is required after the bending unit because the
bent material, for instance wires or robes, is conveyed into
this area and is pivotably moved during the manufacturing
process, depending on the bending direction. This results in a
reduction of the possible output.
It is therefore the object of the present invention to provide
a bending machine with which it is possible to increase the
output of the bent material in an easy way.
This object is achieved with the features of claim 1.
According to the invention there is provided a bending
machine, particularly in the form of a rope bending machine.
which comprises a material feed device which conveys the
material, for instance wires and/or ropes, from a reservoir
area towards a bending unit. When viewed in the feed direction
of the material, the bending unit is arranged behind the feed
device. The feed device conveys the material to be bent into
the bending unit in which it is bent by pivoting the bending
unit. The pivotal movement of the bending unit in one
direc~ion yields a corresponding bend of the material, whereas
the pivotal movement of the bending unit into the respectively
other direction yields a correspondingly differently oriented
bend, so that it is e.g. possible to produce bent ropes or
wires with a meandering progression with the help of the
bending machine of the invention. Ropes or wires bent in such
meandering fashion can e.g. be used for producing nets.

The output can be increased with the bending machine according
to the invention in that the material feed device and also the
bending unit are arranged on a rotatable support table, which
results in a joint rotation upon rotation of the support
table, which rotation is oriented such that the bent material
can be oriented towards the stationary deposit table for the
bent material. In other words, this means that after the
bending unit the bent material is no longer pivotably moved
along at a large solid angle while e.g. a long rope is being
bent, but it is oriented in the direction of the stationary
deposit table and at best shows slight deflections created by
the bending operation on said deposit table, such deflections,
however, not extending beyond the width of the deposit table.
The subclaims refer to advantageous developments of the
invention.
Preferably, the bending unit comprises two rotatably arranged
rolls between which the material to be bent can be conveyed
and which create the respective bend of the material by
pivotal movement into the one or other direction.
It is in principle possible to arrange two roll assemblies one
on top of the other, said roll assemblies being fed by the
feed device with material so as to double the output.
Furthermore, it is possible that the rotational axis of the
rolls of the bending unit and that of the support table are
aligned. However, a non-aligned arrangement is in principle
also possible.
Further details, advantages and features of the invention
become apparent from the following description of an
embodiment with reference to the attached drawing.
The sole figure of the drawing shows a schematically strongly
simplified illustration of the principle of a bending machine
1 according to the invention, which bending machine may
particularly be designed as a rope bending machine.

The bending machine 1 comprises a material feed device 2 which
advances or feeds material 6, particularly in the form of
wires or ropes, from a material reservoir 9 towards a bending
unit 3. The feed direction with a roll assembly 10 is
illustrated with arrow V in the drawing, which reveals that
the bending unit 3, viewed in this feed direction V, is
arranged behind the feed device 2.
The feed device 2 and the bending unit 3 are secured to a
support table 9, which is rotatably supported according to the
double-headed arrow DAT. To this end the support table 9
comprises a corresponding drive device, which is however not
shown in more detail in the figure.
In the example, the bending unit 3, in turn, comprises two
bending rolls 7 and 8 that are rotatably supported via a
further drive in accordance with the double-headed arrow DBR,
the bending direction of the material following from the
direction of the pivotal movement according to said double-
headed arrow.
Furthermore, the bending machine 1 is provided with a deposit
table 5 which is arranged to be stationary so that the support
table 4 can perform a relative rotation with respect to said
deposit table 5, which has the effect that the bent material
6' is oriented such that it comes to rest on the deposit table
5, which considerably increases the output of the bending
machine 1 according to the invention.
