  • Patent number: 11399547
    Abstract: A stamping device serves to create one or more rows of endless dough rings. The stamping device has a stamping head with a stamping punch or a plurality of stamping punches, wherein each stamping punch is associated with a dough ring row. A dough piece support of the stamping device has a dough piece holder or a plurality of dough piece holders. Each dough piece holder of the dough piece support is associated with one of the stamping punches. An opening for the associated stamping punch is configured in a dough piece holder or in each of the dough piece holders as a die. A stamping device results in which the stamping of dough rings in particular to produce doughnuts can also be used, for example, for baking by hand.

  • Patent number: 7648356
    Abstract: A system for producing a strip of dough from a strip of raw dough has a bottom pressing device and an upper pressing device with an interposed processing gap for the strip of dough. The pressing devices each have a plurality of planetary rollers that are rotatably driven about their longitudinal axes in each case. In the circumferential direction the planetary rollers are equidistantly distributed about a common central primary axis that extends parallel to the planetary longitudinal axes. The planetary rollers are jointly driveable so as to rotate about the primary axes. Each planetary roller has a middle part coming into contact with the strip of dough, and removably connected to the ends thereof and integral in rotation therewith shaft stubs. The latter are axially and radially supported on frontal head plates of the pressing devices. The dough-strip production system is easy to clean.

  • Patent number: 7409904
    Abstract: A baking oven comprises a feeding portion having a feeding aperture for introducing dough pieces, a baking chamber and a discharge portion having a discharge aperture for removing dough pieces. In addition, a circulating air unit is provided which comprises a circulating air source generating a circulating air flow, a circulating air heating means and a circulating air guiding channel a part of which is formed by the baking chamber. A plurality of receptacles for dough pieces are mounted in the baking chamber to be freely rotatable or pivotable around a horizontal rotation or pivot axis. The rotation or pivot axes of the receptacles are located higher than the centre of gravity of the receptacles even if the receptacles are filled with dough pieces. As a result, a baking oven is provided in which the dough pieces can be distributed as evenly as possible and moved along during the baking process.

  • Patent number: 7230362
    Abstract: An electric-motor driven actuator has a housing, in which a motor and a carrier plate are arranged and the carrier plate is connected in a fixed manner to a brush holder. The brush holder has a first brush holder which is rigidly connected to the carrier plate. A second brush holder component is also provided which is mechanically coupled to the first brush holder component and is decoupled in a vibration-neutralizing manner from the first brush holder component via at least one damping element and which holds brushes via which contact can be made with a commutator of the motor.

  • Patent number: 5924326
    Abstract: In order to be able to adjust the axial play of a shaft in a shaft holder using a universal buffer component (1) for each unit in a production series, despite a wide tolerance range within the series, a buffer component is mounted so as to be rotatable in the shaft holder (3) at right angles to the axis of the shaft (2). The buffer component (1) is further provided with a circumferential buffer surface which is eccentric with respect to its axis of rotation (4.1). This buffer surface preferably follows an Archimedean spiral and is advantageously made up of individual buffer surfaces (F1-F14). The surfaces (F1-F14) extend tangentially to the Archimedean spiral and each have a buffer region disposed at right angles to the shaft (2). The buffer region is radially set back relative to the trailing edge of the buffer surface in the direction of rotation. The length of this set back corresponds to the desired, nominal axial play ("a") to be set for the shaft (2).

  • Patent number: 5566592
    Abstract: An adjusting drive having a gear housing sealed by a gear-housing lid, with a gear wheel or driver rotatably or sluably supported therein. An axial bearing neck is premolded on the gear-housing lid. A radial inner bearing projection concentric to the driver is premolded on the driver and provides a bearing arrangement inside the bearing neck. A radially outer bearing projection is also premolded on the driver and tangentially and sluably supports the gear wheel.

  • Patent number: 5528093
    Abstract: To integrate electronics with a drive unit, given a simple manufacturing or assembly, and a compact type of construction, a printed-circuit board, which accommodates the electronic components and which is designed, at the same time, as a brush-holder plate for the commutator motor, is arranged, together with an electronic housing, parallel to housing flanges of a motor housing, of a gear housing. The printed circuit board of the drive unit, and is covered on its one axial side by the motor housing and the electronic housing, and on its other axial side by the gear housing thereby protecting it from external elements.
