The present invention relates to a machine for Cutting of long, narrow strips of material webs laid in rolls, in particular of carpeted floor coverings, which are presented horizontally in brackets or in special unwinding devices.

; We are already facilities for cutting webs of goods NEN known, but without exception wide webs can be processed with single or a few knives. These facilities are great for trimming large areas S-bridges provided.

In accordance with the present invention there is now a machine for cutting narrow strips of material webs, in particular carpeted floor coverings, indicated with the long Strips from 1 - 400 mm can be cut.

Such a machine according to the invention is characterized by this from that the machine has a pair of conveyor rollers, between which the web is guided so that against the driven lower roller the upper roller (i) is resiliently pressed by pressure pieces (2)

A holder (3A) with inserted guide racks (3) is also attached above the machine ^{table (11 N in the direction of movement of the goods).}

Take hold of the recesses in the guide rake (3) Circular or curved knives (5) inserted in special holders (7) on the knife shaft (4)

The circular knives (: 5) cut against those in the table profile attached lower knife (6), whereby by turning the croissant knife (5) the web is cut into strips.

The circular knives (5) are on the knife shaft (U) in don Holders (7) axially boweglich stored and are by compression or disc springs in the end area of the by the lock nut (8) adjustable axial play.

In contrast, the lower blades (6) are on a parallel gram holder attached and adjusted so that the necessary contact pressure is generated by the bracket (7).

The width of the strip can be adjusted by moving the brackets (7), by deliberately removing croissant knives (5) and through Replacing the lower knife (6) can be adjusted.

Once the web has passed through the circular knives (5), the product, which is now cut into strips, is replaced by a second one The pair of rollers (9) are detected and transported by the machine.

The upper protective cover (ίο) must be opened to adjust the circular knives and to set up the infeed. with the entire power supply to the machine gutted is.
