- the notching device on four notching strips, which are arranged in a transverse plane of the passage and each movable by a separate drive between a rectangular cross section of the passage releasing starting position and a dipping into the strand notch position.
- the notching strips and the drives are each arranged on a transversely extending to the passage frame-shaped support, with which they form a support module.
- the device is provided with a cutting device for cutting the strand into the notches produced by the notching strips.
- the notching strips may be so-called undivided or split notching strips.
- Undivided notching strips have a wedge-shaped cross-sectional shape.
- Divided notching ledges are each formed by two chamfering ledges extending side by side in the circumferential direction of the conveying passage and spaced apart from each other in the longitudinal direction of the conveying passage, the cutting means comprising a cutting wire extending between the chamfering bars across the conveying passage or through the conveying passage Notched ridges when notched limited cross-section is movable. In the presence of undivided notching strips cutting longitudinally offset after notching takes place in a particular cutting plane.
- a plurality of notching devices with associated cutting devices along the passage can be arranged one behind the other and be actuated substantially simultaneously, wherein the Anfasraun are each movable by a pair of piston cylinders, each at the Rear side of a frame-shaped carrier are held.
- the Anfasraun extend so far in the longitudinal direction of the passage through the through hole in the associated frame-shaped carrier to the front side, so that the gap between two belonging Anfasangn is located between two support frame.
- the associated cutting device is arranged so that the cutting wire between these support frame in the gap between the Anfasraun is movable across the passage.
- the invention has for its object to improve the notch drive in a device according to the preamble of claim 1 or 3. Furthermore, the notch process and the notch quality are to be improved.
- the invention is based on the finding that, due to the presence of a notching strip arranged on one side of the passage, a drive movement directed in a circumferential direction of the passage is particularly favorable and should enable space-favorable designs for the notch drive.
- This drive movement is particularly favorable when a plurality of notching strips are arranged on several sides of the passage.
- the drive elements are each drivingly connected to a base element of a transmission, that converts a directed in a circumferential direction of the passage movement of the base element in the transverse movement of the associated notching strip.
- a directed in the circumferential direction of the passage drive movement is utilized, the direction and effective range allows a space-favorable arrangement and design of the associated notch drive part. It is therefore possible to realize a space-saving construction of the notch drive parts, which has a small dimension in the longitudinal direction of the passage, and is therefore particularly well suited for the notch drive.
- the invention is further based on the finding that the drive movement extending in the circumferential direction of the passage makes it easier Way allows to connect the distributed on the circumference arranged base elements of the notch drive with each other, so that the notch strip can be moved not only simultaneously, but also with a common drive motor.
- the notch guide for the notching strip is arranged obliquely, wherein it includes an acute angle with the following in a circumferential direction of the passage horizontal or vertical.
- the score bar performs a lateral transverse movement corresponding to the magnitude of the skew with respect to the vertical longitudinal plane of the passage, which also has a positive effect on the notches and in particular on the notch quality.

- a further advantage of the invention is to move the at least one notching strip in each case with a drive element that is drivingly connected to a base element of a transmission in such a way that a movement of the base element directed in a circumferential direction of the passage converts into a transverse movement of the associated notching strip.
- This embodiment makes it possible to perform the notches with a desired notching speed, which can be determined by the transmission ratio of the transmission.
- different transmission designs can be integrated, with a simple and small construction for the transmission can be realized.
- a connecting rod is very well, which converts the directed in the circumferential direction movement of the base member in the transverse movement of the notch strip.
- the arrangement of a connecting rod further allows a degressive notch speed when notching, which has a favorable effect on the increasing displacement of the material to be notched during notches.
- a connecting rod can generate a notch progressive notch force.
