  • Publication number: 20190200622
    Abstract: A rotary dough molding machine (10). The machine has a frame (6), a die roller (4) and a feed roller (5) rotatably mounted to the frame (6) and an adjuster that adjusts the gap between die roller (4) and feed roller (5), wherein one of the rollers (4, 5), is an adjustable roller, which is movable relative to the frame (6) by the adjuster. The adjusting has a first drive (1) acting on the first end (51) of the adjustable roller (5) causing a movement of said first end (51) in a first direction (x) transverse to the rotational axis (50) of the adjustable roller (5), and a second drive (2) acting on the second end (52) of the adjustable roller (5) causing a movement of said second end (52) in a second direction (x?) that is essentially parallel to the first direction (x). The first drive (1) and the second drive (2) can be actuated independently of each other.

  • Publication number: 20190021345
    Abstract: A laser arrangement cleans baking surfaces configured in a relief-like manner and optionally cleans evaporation and/or sealing strips of baking plates of a baking machine. The laser arrangement has a laser source for outputting a laser beam onto a locally selectable target area by continuous variation of the output direction of the laser beam and traversing a contour forming the target area. Deflecting optics are arranged at a distance from the laser source and in the target area of the laser source for deflecting the laser beam and for projecting the target area formed by the contour onto the baking plate to be cleaned along a projection direction. The deflecting optics has a device for adjustment for varying the projection direction and the outlet direction of the laser beam.
