Patent DE-4208440-A1 (DE)
Inventor: HEUDECKER GERHARD
IPC: B67B3/12
Filed: 1992-03-17
Abstract: In the case of a method for sealing a bottle by deforming a crown cork which has been placed on a bottle mouth, a holding element (4) positions the crown cork on the bottle mouth in a positioning phase. In a sealing phase, the crown cork is pushed through a conical input region into a sealing end (6) of the sealing device (7), and in the process is deformed and fixed on the bottle. After deformation of the crown cork, an ejection element (8) pushes the crown cork out of the sealing end (6) in an ejection phase. In order to seal the bottle in a simple and reliable fashion without breaking the bottle, with much less pressure and virtually without head pressure during the sealing phase, the holding element holds the crown cork essentially without pressure on the bottle mouth during the positioning and sealing phase and the ejection element for the pushing out of the crown cork in the ejection phase is pretensioned in a pretensioning phase which follows the sealing phase. <IMAGE>

Title: Automatic cutter head for shaping the edge of fabric - has mechanism to form curved shapes and sensors to ensure accurate patterns, while allowing for irregularities in the fabric
Inventor: BIEGGER ROLAND
IPC: B23Q35/40
Filed: 1992-04-16
Abstract: A cutter head has (a) means for severing the fabric, (b) a frame and (c) drive to direct the cutter head. In the head are optoelectric sensors to direct the cutter along a curve. The sensors utilise two sources of light, which project at different angles to a position relative to the cutting point, and the direction of movement of the head is controlled by the coordinates of the fabric and the time of forward movement in conjunction with the sensors. The fabric is pref. usually curtain material (TB), which requires a shaped pattern (LS) along one side. The fabric pref. moves automatically along a table in direction (LR), and is cut by a hot wire element, or a laser, so that the section (12) is cut away from the body (11). The cutter head (10) is pref. mounted on an arm (8), which moves back and forward under control of the parallelogram (5, 6) and cross bar (7), connected to the base (2), in which a step motor (3) can actuate the required movement. The head (10) is pref. in two parts, with a top and bottom disc, holding optoelectric sensors and projectors, which are LEDs and lenses, projecting crosswise, so that one is under the edge of the fabric, and is not activated, whilst the other is in the gap behind the cutter and so is activated. At each step along the fabric as it progresses, along with the relative signals from the sensors, the steop motor is driven in the required direction to form a shape of a curve at the edge of the fabric. The loose edge (12) of the fabric cut away, is directed by the bar connecting the top disc to the bottom disc, to form a gap (LS) through which the light can project to the sensor. The distances between the position of light projectio and the cutter element takes into consideration any irregularities in the fabric, so that the curved pattern is of the correct shape. ADVANTAGE - The design of the cutter head is arranged to take into consideration the uneveness of the fabric which moves automatically forward along a table, so that the curves formed are regular.

ADVANTAGE - The internal nozzle allows the total amount of combustion gas to be adjusted without altering the geometry of the combustion flame. There is no danger of an increase NO- or NOx- emission and the flame can be adjusted to give a max. heat.
