DE360917C - Device for trimming cigars, cigarillos and cigarettes - Google Patents

Description

The subject of the invention is a method for trimming the wrapped cigar, cigarillo or cigarette, as well as a device serving this method, which effects the trimming without any change in shape and without displacement of the cut with tobacco drawn over by the knife. The method can be used with a single-acting machine; But it is still much more advantageous for cigarette machines with a wide winding surface, the long product of which has to be cut through once or several times for the production of the shorter finished product. Experience the \ ^r consists essentially in that the vorrollende wrap fold over in the wrapping table, that the rolling surface is lying, out of the same protruding or vortretende diameter rollingly after already immediately after attack the fold at the feed trough, the supernatant from the rolling fold tobacco mass was removed by advancing knives. The advantage of this method is in contrast Ü5 to the known trimming of and make as after leaving the wrapping table except for the introduction has been said that the inevitable knife pressure of cutting on the fixed Decisions winding in the roll towel on, the solid support of the table takes place, thereby secure the vSchnitt and used sharper and the roll sheet is significantly spared.

An embodiment of a machine which serves this method is shown in the drawing shown in Fig. 1 in a longitudinal section through the same, in Fig. 2 in the Top view, in Fig. 3 in cross section at the knife point and in Fig. 4 in cross section through the sled.

The changing table α is provided with the insertion trough b in a known manner. The carriage d, which carries the roller blanket c , runs over the same, on lateral strips e; the roll sheet p is placed over the machine in a known manner and fastened by clamps f, g. In the front end is the collecting trough h for the finished product.

On both sides of the changing table α leads a U-shaped bracket i, at the open ends of which a knife k sits directly in front of the trough b , and which is held by spring I in the rest position.

The changing table receives, depending on its width or intended work, near its front end recesses m; the cutting edges of knives n protrude through this, appropriately rising at an angle, which are fixed by adjustable clamping devices 0 below the plane α.

The roller blanket c in the carriage d is provided with grooves t corresponding to the position of the knives η or subdivided accordingly so that it passes freely over the knives protruding over the rolling surface. The roll cloth is slit at the knife points.

The operation of the machine results from this as follows:

After inserting the tobacco into the folds of the roll-up cloth lying in the trough b , the carriage d is pulled forward in a known manner, and while it rolls over the trough, the knives k are brought to cut off the tobacco pieces protruding over the sides of the roll-up sheet by hitting the handle i. The roll cloth fold with the roll has meanwhile rolled over the knife edges η , the roll is cut accordingly and thrown into the collecting trough h in a known manner.
