Definitions
- the invention relates to a device for producing a curved band, in particular a curved flat line assembly, consisting of a drive device with rotating clamping elements connected downstream of a weaving device.
- the first variant is that the surface of the tapered rollers is made up of lamellae and the diameter is set differently by moving the lamellae differently on both sides of the roller.
- a turret roller magazine is provided in which tapered rollers are provided for both senses of curvature and the different radii of curvature.
- the invention has for its object to provide a flexible, inexpensive, space-saving device with a wide range of applications.
- the object is achieved in that at least two take-off rollers are arranged in a frame, of which at least one take-off roller is driven.
- the frame can be pivoted about an axis perpendicular to the plane of the belt.
- the pivot axis of the frame can also be moved transversely to the direction of movement of the belt.
- the take-off rollers can advantageously be profiled according to the thickness profile of the belt.
- the non-driven take-off rollers pressure rollers
- the take-off rollers can have a freewheel.
- FIG. 1 shows the schematic representation of the device according to the invention and FIG. 2 shows a top view of the device according to FIG. 1.
- the device (Fig. 1) contains a take-off roller 1 and a pressure roller 2, between which the warp threads run in the form of individual lines 3.
- the roller drive 4 engages in the take-off roller 1.
- Take-off roller 1, pressure roller 2 and roller drive 4 form the take-off device.
- This is mounted on a swivel frame 5, which with the swivel axis Z With the help of a hydraulic cylinder 6 (Fig. 2) is pivotable.
- the swivel frame can be displaced on a sliding bed 7 in the weaving plane and perpendicular to the running direction of the individual lines 3.
- the pivot axis Z of the swivel frame 5 can be placed on the edge of the line assembly to be removed, which is to form the associated inner radius during the production of the bend.
- the radius of curvature is determined by the degree of pivoting of the trigger device. If the swiveling-out is 00, the pull-off device pulls off the line assembly like a conventional pull-off device, and a straight band is produced.
- the take-off rollers 1, 2 are additionally pivoted about the pivot axis Z while maintaining the rotational speed. As a result, a greater length is subtracted from the individual lines lying away from the pivot axis Z than from the individual lines closer to the pivot axis Z. There is a curvature.
- the total amount ⁇ of a single swivel is limited.
- individual curvature sections are lined up.
- the rotational speed of the take-off roller is increased so that the largest possible individual swivel ⁇ is achieved so that the drive device can swivel back quickly without the occurrence of compression in the belt.
- the take-off rollers can be divided into segments which - each segment by itself - have a freewheel mechanism which counteracts the possible formation of compression when swiveling back.

Abstract
L'invention concerne un dispositif de production d'une bande incurvée, en particulier d'un câble composite plat incurvé, comprenant un dispositif d'entraînement comportant des éléments de serrage rotatifs, monté à la suite d'un dispositif de tissage. Il est en outre prévu au moins deux rouleaux dévideurs montés dans un bâti, dont l'un au moins est moteur. Le bâti est monté pivotant autour d'un axe perpendiculairement au plan de la bande. L'axe de pivotement du bâti peut, par ailleurs, être décalé perpendiculairement au sens de déplacement de la bande. Les rouleaux dévideurs peuvent être profilés en fonction du profil d'épaisseur de la bande. Les rouleaux de pression non entraînés peuvent être formés par des segments de différents diamètres qui sont placés sur un axe fixe. De préférence, les rouleaux dévideurs sont munis de moyens de rotation à roue libre.
