The invention concerns combined Richtund bending machine for more drahtoder band-shaped material, with a transport device for the intermittent feed motion of the material strand around desired amounts, a direction device for the straight line arranging of the material strand, measuring instrument for measuring the respective Straugvorschubweges, required operatable bending device for bending the material strand, a longing oath device for separating a strand section and if necessary an ejection device for the separated strand section. Such machines can be also only used as view machines for material taken off from Bunden, if the bending device in such position is stated that it does not obstruct the feed motion from the Bunden of the taken off and at the Bichtvorrichtung led past MaterialI0 of strand. Since the lengths of the strand sections almost-arranging from view machines vary in practice within very far borders, the straightening machine for long Strangabschnitto Auslaufeinrichtungsn must be connected at the outlet side as well known, which lead from the Bichtmaschine withdrawing Strangabsohnitte and in each case after completed discharge in such a manner placings that the discharge of the next strand section is not obstructed. In the case of use of a combined Bichtund bending machine for arranging in this connection difficulties, because in the environment of the bending device a relatively large free surface, a so-called Biegetisch, must be planned, result those normally to the drag axis of the bending tool and usually under an angle of for instance 45o against the horizontal bent arranged are and for the support and guidance the curved from the construction of the bending machine. even shaped part, e.g. a concrete clip, serves. Since when putting the material strand forward by the direction device and the bending device the free end of the material strand withdrawing from the bending device comes not only easily into oscillations, but with larger lengths of the same according to the force of gravity also along the Biegetisches, is reliable transferring of the material strand at the bending device sinks downward past into the discharge device in question posed. Here the invention, whose task is it to out-arrange combined Richtund Biogomasohino of the introductory indicated kind in such a manner, begins to find dafl it after stopping the bending device also reliable in service as simple view machine use can. This task is solved according to invention thereby that in feed direction of the material strand behind the bending device - u.zw in drop direction of Strangabsohnitten with distance, cut to length by-pushed, at the dormant bending mechanism and, among themselves - at the surface of the machine housing Führungsund a catching border for the strand section, cut to length specifying the bending level, is intended, which are from each other independently from the bending level into a position bewagbar, into which it at the machine housings a guidance gutter and among them a collecting gutter forms. A remark example of the invention is described more exactly now with reference to the designs. Fig.l shows a schematic opinion combined Richtund according to invention bending machine, with which that normally bevels Biegetisch for the simplification of the representation into the layer is turned; Fig.2 is a schematic cross section after the line II-II in Fig.l. In Fig.l one recognizes a bending machine --I--, in the one wire taken off from a not represented federation --D-- for example to handles for the armouring by reinforced concrete to be converted is. The wire --D-- becomes for this purpose by two motor propelable Transportrollanpaaren --2 and 3--, which attack with Reibungssehluß at the wire, by a direction device --4-- well-known design led, in which it is straight-arranged. Behind the direction device is a pair of measuring roles --5-- planned, which serves for the drive of a pulse generator for an electronic length measuring device, with which the feed motion of the wire is measured, over as a function of it bending and finally separating desired wire sections by means of a downstream flocks --6-- steer automatically to be able. Behind the shears the wire arrives at the bending device --7--, their substantial components a bending thorn being certain with the bending procedure --8-- and around its axle --9-- tiltable bending tool --10-- it is which are favourably so trained and stored that them for the change of the sense of direction of the bending procedure their relative relative concerning the wire --D-- to exchange can. A bending machine with this structure is for example in at-PS 314319 more exactly descriptive. As is suggested in Fig.2, is as drag axis of the bending tool --10-- serving thorn axle --9-- under 45° against the horizontal bent and it runs perpendicularly to a diagonal surface specifying the bending level --11-- the R4aschinengehäuses, the Biegetisch is called and with the bending procedure as supporting surface for the ironing hurry already bent serves. The length of the thighs of the handles which can be bent and the angles between the individual handle thighs are entered in practice into a not represented program expensive mechanism, which causes then manipulation of the pinchrolls, the bending tool and after the completion of the handle the manipulation of the shears for separating the handle from the approaching wire. In order to then divide the ability of the descriptive bending machine, the wire taken off from a federation almost-arranged and without execution of bending procedures into arbitrarily selectable length sections, without being able to use danger of unwanted vibrations or deformations of the wire by force of gravity effect despite long wire sections, is behind the bending machine in a distance, which is sufficient, in order to avoid with the handle bending a handicap of the bending procedures, a discharge device --12-- actually admitted of structure arranged, essentially out. one with the inlet direction of the wire --D-- eingefluchteten, downward öffenbaren photograph gutter --13-- and one toward parallel to the Biegetisch --11-- diagonally under it arranged catch pan --14-- exists. In the Biegetisch --11-- among themselves two rectangular, fold-like trained borders are in drop direction --16, 17-- planned, those for example by means of actuators --18, 19-- are tiltable. In resting position the borders lie --16, 17-- in of the Biegetisch --ii-- fixed bending level, so that they do not obstruct bending procedures. If the descriptive machine is however only as [generator to be used, then the borders become --16, 17-- into the position shown in Fig.2 swivelled. The border --16-- forms now together with the Biegetlsoh --11-- a V-shaped guidance gutter --26-- for at the unactuated bending device --7-- by-pushed wire, by which the wire not only prevented from vibrating, but at the same time to the discharge device --12-- one passes on. After separating a wire section of desired length the guide rail becomes --16-- by the actuator --18-- briefly again into the level of the Biegetisches --ii-- swung. With it also the Aufnahmerlnne becomes simultaneous --13-- the Auslaufvorrlohtung --12-- opened and the separated wire section --A-- can now in of the catching border --17-- formed collecting gutter--27-- and in with this escape-end catch pan --14-- the discharge device --12-- down-slide. At the same time with the back swivelling of the Auffanglelste --16-- also the bending device can --7-- either behind the bending table level to be withdrawn, in order not to obstruct an unreeling of the wire section, or however it can in the bending device --7-- an ejector intended its, which out-pushes the wire section from the bending device. The invention permits naturally different modifications. For example can in place of swing-out borders --16, 17-- also adjustable borders to be planned. If the machine is to be used intended only for separating short wire sections, then the discharge device can --12-- also been void and the wire sections cut to length can in the collecting gutter --27-- are collected.

The combined straightening and bending machine for wire-shaped or strip-shaped material has a transport device (2, 3) for the intermittent advance of the material strand, a straightening device (4) for straightening the material strand, a measuring device (5) for measuring the respective strand advance travel, an occasionally actuable bending device (7) for bending the material strand, and a cutting device (6) for severing a strand portion. A guiding and a collecting fence (16 and 17) for the strand portion cut to length are provided behind the bending device (7) in the direction of advance of the material strand (D), on the surface of the machine housing which determines the bending plane (1). These fences are movable independently of one another out of the bending plane (11) into a position, in which they form, on the machine housing, a guiding channel and, underneath it, a collecting channel. <IMAGE>
