Embodiment Construction

[0015] Further preferred features and embodiments of the invention can be seen from the subclaims and the detailed description which follow. Two particularly preferred embodiments and methods will be described in detail below with reference to the accompanying drawings.

[0016] The apparatus shown is used to clean cubic boron nitride coated abrasives used for grinding tobacco cutting knives in a tobacco cutting machine.

[0017] figure 1 The device 10 shown in Fig. 1 shows a cutting knife 11 of a device (not further shown) for separating tobacco leaves from tobacco cake. For separating the tobacco leaves, single or several cutting knives 11 may be arranged on a cutting plate for forming a front cutter, a cutting drum for forming a drum cutter, or other knife supports. Instead of the cutter, other separating elements with cutters can also be used. Preferably, the tips 12 of several cutting knives 11 define a cutting plane 13 . A grinder 14 is also arranged in the region of...

Abstract

The cleaning-off device is used in the process of cleaning boron nitride off a grindstone. The grindstone (14) is in the region of a separating element, and liquid or gas (16) is applied in the region of the grindstone by means of a jet element (17), which applies a cleaning jet (18) of liquid or gas to the grindstone parallel to the separation line.

Description

technical field [0001] The invention relates to a device for cleaning a grinding tool coated with cubic boron nitride in a device for separating tobacco leaf from a cake, wherein the grinding tool is arranged in the region of a separating device accommodating at least one separating element In order to grind each separate element, means for cleaning the grinder are provided in the region of the grinder. In addition, the invention relates to a method for cleaning abrasives coated with cubic boron nitride in a device for separating tobacco leaf from tobacco cake, the method comprising the steps of separating tobacco leaf from tobacco cake by means of at least one separating element. Separation, grinding each separation element with the coated abrasive and cleaning the abrasive. Background technique [0002] During tobacco leaf separation, preferably during tobacco leaf cutting, the separating element, preferably designed in the form of a knife, is reground during tobacco leaf...
