DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] The blade holder 1 shown in the figures includes a fixing device 15, with which the blade holder 1 is displaceable along a traverse 13 of a longitudinal cutting machine 7 and with which the blade holder 1 can be fixed to the traverse 13. For this, the fixing device 15 includes a dovetail guide 16, with which the blade holder 1 can be displaced linearly along the traverse 13. The fixing device 15 further includes a clamping element 17, with which the blade holder 1 can be fixed at a desired location on the traverse 13.

[0032] The blade holder 1 also includes a blade head 3, to which a circular blade 4 is attached. The blade head 3 can be lowered by means of an actuator 8 having an energy supply 12. The blade head 3 can be moved linearly towards a lower blade 9 automatically by means of the actuator 8. The actuator 8 can be actuated electro-mechanically, hydraulically, or pneumatically. For example, the actuator 8 upon receiving respective signals from a control unit can move the blade head 3 linearly up and down.

[0033] The blade holder 1 also includes an adjusting slide 5 for positioning the blade holder 1 on the traverse 13. The adjusting slide 5 has a contact element 6, whose relative vertical position corresponds with the position of the cutting edge 18 of the circular blade 4. The starting position of the adjusting slide 5 is shown in FIGS. 1 and 2.

[0034] For positioning of the blade holder 1 on the traverse 13, the adjusting slide 5 is pivoted downward into its positioning position. When the adjusting slide 5 is in its positioning position, the clamping element 17 of the fixing device 15 is untightened and the entire blade holder 1 is moved along the traverse 13 until the contact element 6 is aligned (brought into contact) with a cutting edge 10 of the lower blade 9 or with another reference surface 14 of the lower blade 9 (see FIGS. 3-6). In the aligned state, also the blade head 3 and the circular blade 4 are aligned with the lower blade 9. After this alignment the clamping element 17 of the fixing device 15 is tightened and thereby the blade holder 1 is fixed to the traverse 13 again. Also, the adjusting slide 5 is pivoted back into its starting position. This alignment movement of the blade holder 1 takes place parallel to an axis of rotation of the blade head 3.

[0035] Accordingly, as soon as the blade holder 1 is aligned/positioned on the traverse 13 by contact of the contact element 6 with the cutting edge of the lower blade 9, the blade holder 1 is fixed by means of the fixing device 15. For the following cutting process, the blade head 5 is automatically lowered (actuated) by means of the actuator 8.

[0036] The present invention contemplates providing a mechanism 11 which may be activated by a switch 2. The mechanism 11 is activated by the switch 2 as soon as the adjusting slide 5 is pivoted out of the starting position shown in the FIGS. 1 and 2. The switch 2 is coupled with the actuator 8 via the mechanism 11, such that (automatic) lowering (actuation) of the blade head 3 is prevented, when the switch 2 is activated. For example, the mechanism 11 activated by switch 2 interrupts the power supply 12 to the actuator 8.

[0037] Accordingly, as indicated in FIG. 7 the present invention contemplates that the blade head 3 cannot be automatically actuated by the actuator 8 as long as the adjusting slide 5 is moved out of its starting position. Thus, the blade holder 1 can only can be used for a cutting process when the adjusting slide 5 is moved back again into its starting position. In this manner, the lower blade 9 is prevented from being damaged by the adjusting slide 5 that has moved out of its starting position during an aligning process of the blade head 3.

[0038] The features of the subject matter of this invention set forth in the above description, the patent claims, the abstract and the drawings can be used individually and in any desired combination for the realization of the invention in its various embodiments.

[0039] The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawings, but also encompasses any modifications within the scope of the appended claims.
