Embodiment Construction

[0035] figure 1 and figure 2 A schematic diagram of a cutting device 1 according to the invention is shown for cutting thin, sticky strips such as cord strips for the manufacture of tyres. The cutting device 1 comprises as indicated by the double arrow P 1 The upper knife 2 which can move vertically and the lower knife 3 which is fixed in position are shown. A pulling device 4 is also provided, which comprises a gripping section 5 for pulling the strip section of the strip 6 to be cut past the cutting device or the two knives 2 , 3 .

[0036] A hold-down device 7 is also provided, which includes a magnetic strip 8 for securing the strap. Pressing device 7 as indicated by the double arrow P 2 Vertical movement is possible as shown, for which a drive unit 9 is provided. In the example shown, the drive unit 9 comprises two belt drives 10 arranged on both sides of the hold-down device 7 . The belt drives 10 each comprise a belt 11 connected to the hold-down device 7 . The ...

Abstract

The invention relates to a cutting device for cutting a thin and adhesive belt, in particular a cord belt. The cutting device comprises an upper knife, a lower knife, a pulling device for pulling a belt material to be cut, and a holding-down device, of which the top side can be placed on a belt. The holding-down device comprises a magnetic strip for fixing of the belt. The magnetic strip works jointly either with a metal element in the belt or a clamp bar arranged under the belt, jointed to the lower knife and being vertically movable, so that the front edge of the belt is lifted to be grabbed by a gripping portion of a traction device. The magnetic strip presses the belt from the upper side onto the lower knife or the clamp bar on the position of the hold-down device. The hold-down device (7) is provided with a hold-down bar (20) arranged in from of the magnetic stripe (8) and facing the direction of the pulling device (4). The magnetic strip (8) is vertically movable relative to holding-down bar. When the holding-down device lowers down, the holding-down bar moves the belt (6) and presses the belt, and the magnetic strip (8) is then moved to the belt (6).

Description

technical field [0001] The invention relates to a cutting device for cutting thin and viscous tapes, in particular cord tapes, the cutting device comprising an upper knife and a lower knife, a drawer for pulling the tape section to be cut through device, and a pressing device that can be seated on the belt on the upper side, the pressing device includes a magnetic strip for fixing the belt, which is either directly connected to a metal element contained in the belt or to a metal element arranged on the belt The vertically movable clamping strips below the strip and overlapping the lower knife work together so that the strip can be lifted with its leading edge to be grasped by the gripping section of the traction device, wherein the magnetic strip The strip is pressed from above directly onto the lower knife or clamping strip at the point where the strip is pressed. Background technique [0002] Such a cutting device is known, for example, from DE 10 2009 037 506 A1. The cu...
