Definitions
- Device for longitudinally dividing material webs with several cutting devices that can be arranged side by side
- a plurality of cutting devices fastened to a cutter bar which have a carrier body which is provided with a controllable lowering device on which a circular cutter is rotatably mounted on a cutter head.
- the individual cutting devices are displaceable and fixable, if necessary detachably attached to the cutter bar, so that the desired cutting widths can be set by adjusting the mutual distance between adjacent cutting devices.
- the invention has for its object to provide a device for slitting material webs, which makes it possible to use very narrow cutting devices without changing the length of the guide carriage, which enables an arrangement of cutting devices on the cutter bar "close to close”.
- the object of the invention is achieved by a device for longitudinally dividing material webs with a horizontal cutter bar on which a plurality of cutting devices can be arranged next to one another at an adjustable distance, each of which has a carrier body on which a circular knife is mounted, and with pairs of guide strips on the cutter bar running parallel to one another, on which the cutting devices are guided such that they can be locked, two pairs of guide strips extending in a first guide plane and at least one further pair of guide strips extending in a second guide plane which runs parallel and at a distance from the first guide plane.
- the arrangement of at least one further pair of guide strips in a second guide plane offset from the first guide plane makes it possible to use cutting devices which are significantly narrower than the previously known cutting devices, but the guide carriages previously used can still be retained.
- the cutting devices guided on the pairs of guide strips of the first guide level are no longer directly adjacent to one another, but a cutting device is arranged between each one, which is guided on the pair of guide strips running in a second guide level.
- 1 is a front view of a cutter bar with several cutting devices
- Fig. 2 shows a vertical section. the line II-II in Fig. 1st
- FIG. 1 shows a cutter bar 1 of a device for longitudinally dividing material webs, on which five cutting devices 2.1, 2.2 and 2.3 are fastened in a group "close to one another".
- the cutting devices 2.2 and 2.3 are additionally shown at a distance from one another for clarification.
- the cutting devices 2 each have a carrier body 3, to which a cutter head 4 with a circular knife 5 is fastened and lowered in the vertical direction.
- the knife head 4 is covered by a hand guard so that only the lower cutting area of the circular knife is visible.
- the individual circular knives each work against cutting rings 6 which are fastened on a knife shaft 7 at a distance from one another.
- the individual cutting devices 2 can now be shifted against each other on the cutter bar 1 in the horizontal direction and fixed to one another at predeterminable distances.
- guide strips 8, 9 and 10 each assigned to one another, are provided on the cutter bar 1 as pairs of guide strips, on which the carrier bodies 3 of the cutting devices 2 are each mounted so that they can be moved and fixed.
- Each cutting device 2 is provided with a guide carriage 11.1 and 11.2 in such a way that the guide carriages of adjacent cutting devices are alternately held on the guide bar pairs 8, 9 and 10 in a cyclical interchange.
- FIG. 2 is in accordance with the section through the cutter bar 1 acc. the line II-II in Fig. 1 shows a partial side view of the cutting device 2.1.
- the guide carriages 11 are indicated with the reference numerals 2.2 and 2.3 placed in brackets behind them.
- pairs of guide strips 8 and 9 extend in a first guide plane 12 on the cutter bar 1, while the pair of guide strips 10 extends in a second guide plane 13 which runs parallel and at a distance from the first guide plane 12.
- the guide carriages 11 are expediently each connected to an adapter slide 14.
- the adapter slide 14 have then identical fastening means on which the individual cutting devices 2 can be releasably fixed. This makes it possible to produce the cutting devices 2 identically and interchangeably, since the connection options given by the adapter slide can be designed identically for the entire length of the cutter bar.
