Abstract
Abstract Apparatus for cutting out dough forms having inner cutouts from a ribbon of traveling dough. Parts of the apparatus include a first pair of rollers, a second pair of rollers spaced apart from the first pair and an endless carrier belt which supports the ribbon of dough and conveys it between each of the pairs of rollers. Each of the pairs of rollers is made up of a cutting roller, with punching elements around its periphery, and a contact pressure roller. The punching elements on the cutting roller of the first pair of rollers cut out the inner cutouts of the dough forms from the traveling ribbon of dough and the punching elements on the cutting roller of the second pair of rollers cut out the outer shapes of the dough forms. When the carrier belt conveys the ribbon of dough between each pair of rollers, the contact pressure roller is in pressure contact with the cutting edges of the punching elements of the cutting roller of that pair. The punching elements on the cutting roller of the first pair of rollers retain the inner cutouts of the dough forms as they roll away from contact with the ribbon of dough, and a blower positioned adjacent that roller blows these inner cutouts into the interior of the roller through openings in the roller wall. A trough shaped conveyor belt in the roller removes the inner cutouts as they accumulate during operation of the apparatus.

Apparatus for cutting out dough forms having inner cutouts therein from a ribbon of dough travelling from a first roller pair to a second rollEr pair comprising: a first roller pair having a cutting roller and a contact pressure roller for the passage of the dough ribbon through a gap between said rollers and for cutting out the inner cutouts of the dough forms; a second roller pair spaced apart from said first roller pair having a cutting roller and a contact pressure roller for the passage of the dough ribbon therebetween and for cutting out the outer shapes of the dough forms; the cutting roller of each of said roller pairs having punching elements with cutting edges on the periphery thereof, said contact pressure roller being in pressure contact with said cutting edges of the punching elements of the cutting roller; means for removing pieces of dough cut out by the first roller pair cutting roller; and carrier means for the dough ribbon during the passage thereof between said first and second roller pairs wherein the dough ribbon is supported by the carrier means in contact with the first roller pair cutting roller over a radial segment of said cutting roller rearwardly of the dough ribbon passage gap in the first roller pair in the direction of travel of the dough ribbon.
Claim 3
Dependent Claim
19 words
Apparatus according to claim 1 wherein said radial segment extends over a radial angle of between 0* and 45*.
Claim 4
Dependent Claim
45 words
Apparatus according to claim 1 wherein the punching elements of the cutting roller of the first roller pair are provided with embossing formations adjacent the cutting edges thereof for embossing an upper surface of the dough ribbon during its passage between the first roller pair.
Claim 5
Dependent Claim
66 words
Apparatus according to claim 1 wherein the punching elements of the first roller pair cutting roller converge towards cutting edges thereof for retaining punched-out pieces of dough within said punching elements and wherein blowing means directed radially onto the periphery of the first roller pair cutting roller is provided for blowing said punched-out piece of dough into a hollow of said first roller pair cutting roller.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 4 wherein said blowing means is directed to a portion of the periphery outside the radial segment of the first roller pair cutting roller.
Claim 7
Dependent Claim
49 words
Apparatus according to claim 4 wherein at least a part of said blowing means is directed onto a portion of the periphery inside the radial segment of the first roller pair cutting roller, the carrier means of the dough ribbon being deflected away from said portion of the periphery.
Claim 8
Dependent Claim
86 words
Apparatus according to claim 1 wherein the punching elements of the first roller pair cutting roller diverge toward the cutting edges thereof for leaving punched-out dough pieces behind on the carrier means, blowing means directed onto a portion of the dough ribbon rearwardly of the first roller pair in the direction of travel of the dough ribbon being provided for blowing said punched out dough pieces out of the dough ribbon, the dough ribbon carrier means being deflected away from said portion of the dough ribbon.
Claim 9
Dependent Claim
85 words
Apparatus according to claim 1 wherein the punching elements of the first roller pair cutting roller diverge toward the cutting edges thereof, wetting means being provided for the carrier means forwardly of the first roller pair in the direction of travel of the dough ribbon to increase adhesion of the dough ribbon to the carrier means to allow the punched-out dough pieces to be separated from the dough ribbon when the carrier means is deflected away from the direction of travel of the dough ribbon.
Claim 10
Dependent Claim
21 words
Apparatus according to claim 1 wherein the punching elements of the second roller pair cutting roller diverge toward cutting edges thereof.
Claim 11
Dependent Claim
32 words
Apparatus according to claim 4 wherein a conveyor belt is provided inside the first roller pair cutting roller for removing the blown out dough pieces in the hollow of said cutting roller.
Claim 12
Dependent Claim
27 words
