SU969A1 - Method and machine for rolling and pulling dough - Google Patents

Description

Machines are known in which the endless belt moves evenly at a certain distance under the fixed board, with parts of the dough rolling between the ribbon and this board, or machines that have two endless ribbons moving in opposite directions for rolling and stretching the separated dough pieces. x, passes at a certain, arbitrary distance one above the other, with the lower ribbon being quickly and evenly fed forward, and the upper ribbon slowly back, and pieces of dough moving between the bands, n and this rolling out in the test are prepared folds.

The proposed method and the machine serve to eliminate the folds formed during the rolling out of the dough, which is achieved by the fact that two endless ribbons between which the dough pieces move, make an intermittent movement in the same direction, but alternately, while in a continuous sequence, then the tape moves some length in this direction, while the top tape remains at rest, then the top tape moves, while the bottom tape remains stationary. As a consequence, it is achieved. that the dough pieces are alternately rolled back and forth, so that the folds arising from the opposite movement roll again in the opposite direction, as a result of which the dough piece receives a smooth and closed surface. A further difference of the proposed machine is that the dough pieces are not only rolled back and forth, but are evenly advanced through the machine, the cutter can directly adjoin the machine to separate the dough.

In FIG. 1 shows a longitudinal section of the proposed machine; FIG. 2 - her plan; FIG. 3 is a cross-section along line ai (in FIG. 1); FIG. 4 is a cross-section along the line c-d (in FIG. 1) and FIG. 5-cross section along the line e - / (in Fig. 1)

Point 1 receives the separated pieces of dough from the dividing machine and falls on the lower endless belt 2, rounding: the left reels 3 and 4, with the upper part of the belt 2 sliding on the flat table 6.

Above the belt 2 there is a second endless belt 7, enveloping the drums 8 and .9, with the lower part of the belt I 7 sliding under the flat board of the bed 10.

Tape 2 moves in the direction of arrow 17, and tape 7 in the direction of arrow 18, with alternate intermittent movement of both tapes limited each time to a small length.

The drive for current movement has the following arrangement: on the shaft 23 of the working and idler pulley 19, the shoulders 20 and 21 are fixed, equipped with free rollers 22 on the axles 22.: The shoulders 20 and 21 are rotated | pulley 19 and one of them enters with his roller 22 into one of four cuts of the Maltese cross 24, j mounted on the shaft 25 of the drum 5 and; thus, the belt 2 is set in motion. Near the cross 24, a second cross 26 is fastened, rotating on the shaft 27 with: another arm 20 and connected with the tongue 28, and the cross strap 29 with the drum 8 and thus sets the belt 7 in motion.

During the rotation of the arms 20 and 21 in the direction of the arrow 31, the last are over-; they place their rollers 22 successively along the cuts of crosses 26 and 24, the latter turning each time by a quarter of a turn, i.e. so that when shoulder 21 emerges with its roller 22 from the notch of the cross 24 and i the latter comes to rest, shoulder 20 enters with its roller 22 into the adjacent notch of the cross 26 and sets the latter into motion. Each time one of the shoulders leaves its roller i from the cut-out of the cross, one of the sectors 32 enters the corresponding groove between i

by the hollows of the cross, owing to the chega, this cross, and with it also the ribbons 2 or 7 brought by them are brought to a rest position. The cross 24 and the drums 3 rotate in the direction of the arrow 5., the cross 26 and the cheek 28 in the direction of the arrow 34, so that by crossing the belt. 2.9 the proper movement of the belt 7 is achieved.

SUBJECT OF THE PATENT.

1. A method of rolling out and stretching the separated dough pieces between two movements in the same direction over each other with endless ribbons, characterized in that alternately one of the belts is in a resting position, while the other is in motion.

2. To carry out the method mentioned in p. /, A machine consisting of two endless ribbons arranged one above the other, between which a dough is rolled, characterized in that, to transmit the movement of the ribbons, yokes 20 and 21, mounted on the shaft, alternately in one direction, provided at the ends with rollers 22 and entering the notches of the Maltese crosses 24, 26, of which the first is fixed on the shaft of the driving drum of the lower belt, and the second on the shaft 27 of the shkiva, transmitting the movement to the drum 8 of the upper ribbon, and Sectors 32, included in the recesses of the blades of the crosses.
