摘要： The machine smoothes stitched seams on shoe shanks and applies a tape to cover the smoothed seam. A driven frictional wheel is cooperable with a second friction wheel rotatably mounted on a relatively elongated support over and along which the shanks are fed, the two friction wheels pressing and smoothing the stitched seams. Two holding elements are releasably engageable with this support at supporting points thereon spaced longitudinally of the support. A control circuit operates in such a manner that the two holding elements initially clamp the support at points spaced longitudinally therealong and, as a shoe shank leaves the friction wheels, the leading holding element is released for passage of the shoe shank therethrough while the trailing holding element remains clamped on the support. As the shoe shank clears the leading holding element, the latter is again clamped on the support and the trailing holding element is released from the support for passage of the shank. As the shank leaves the trailing holding element, the latter is again clamped on the support.

摘要： A sewing machine with a needle bar mounted in a rocker, has a step motor drive for the oscillation of the rocker. A memory is used in which are contained selected digital data for influencing the step motor and a control unit is inserted between the memory and the step motor for selection and conversion of the digital data into stepping pulses for the step motor. A pulse generator operating synchronously with a main shaft of the sewing machine is used for triggering the transmission of stepping pulses to the step motor. To improve the drive transmission and to avoid reactions on the step motor, the step motor is connected to a lever arm of the rocker via an eccentric transmission.

摘要： In a sewing machine with a feed device which comprises a feed wheel arranged next to a stitch formation point, driven synchronously with stitch formation tools, and mounted in a support provided at the housing of the sewing machine, in order to obtain an extremely exact drive in both directions, the feed wheel is placed in driving connection with a step motor. In a manner known in itself, the step motor receives stepping pulses which can be generated by a pulse generator operating synchronously with a main shaft of the machine and via a counting device that determines the feed amount. This feed amount is presettable by selectable digital data contained in a memory. In an arrangement wherein the feed wheel is connected to its drive via a deflection gearing and a transmission shaft mounted in the support, the deflection gearing consists of a ring gear attached to the feed wheel and of a pinion firmly connected to the transmission shaft. An especially compact solution results by attachment of the step motor on the support and by rigid coupling of its output shaft to the transmission shaft.

摘要： Vibrations of pipes or other components installed in a container such as a tank intended for holding liquids, are damped by surface area damping bodies, e.g. plates with through-holes that are immersed in the liquid in the container. These plates are rigidly connected to the pipes or components to be damped. The vibration damping plates are constructed of metal, for example, and the through-holes reduce the mass and advantageously affect the damping effect. The materials for making the perforated damping plates are selected to be compatible with the content of the containers, such as a fuel in a tank in a spacecraft. The surface area ratio of all cross-sectional areas of the through-holes to the total plate surface area is optimized to achieve a maximum damping effect. These perforated plates are secured to pipes, braces, filters, ducts, or other internal components of fuel tanks of land vehicles, aircraft, and spacecraft.

摘要： A method for approaching a predeterminable end point of a seam spaced from the edge of a workpiece, with a sewing machine which comprises an adjustable needle and lower transport, a sensor arranged before the needle and triggering the process for the positioning of the needle in the end point during passage through the edge, a pulse generator coupled with the main shaft of the sewing machine for the delivery of counting pulses for a pulse counter, and a micro-computer which controls the action of the feed means as a function of the pulses originating from the sensor and from the pulse generator. To execute a desired shortening of the length of one or more of the last stitches before the end point of a seam, the workpiece is moved back by the difference between the desired stitch length and the stitch length set by the setting device, before execution of the adjusted feed. For correction of the stitch length executed during the feed phase, the cloth feeder is connected with a switching gear controlled by the micro-computer for controlled switching on during its reversed feed phase which precedes the respective forward feed phase.

摘要： A cover construction for a sewing machine work support column which is adapted to contain a looper and a thread-cutting device comprises an upright support member or column upon which a substantially L-shaped cover member is pivotal. The cover member includes a cover plate portion which extends horizontally in a closed position and covers the top of the device and a side portion which extends vertically in a closed position. The cover plate member is openable to a position opened outwardly from the support member in which position the cover is located in a vertical position and the side portion in a horizontal position. The side portion includes two bearing faces which are defined on the back and the bottom faces thereof, respectively, and which will abut against a top bearing surface of a locking member which is displaceable along the height of the upright support member. In the open position, one bearing face on the side wall is engaged on the locking member and in the closed position, the bottom bearing face engages on the top of the locking member. The locking member is biased by a coil spring around the mounting member in an upward direction in which it contracts the bearing face on the side wall in an open position of the cover and the bearing face on the bottom wall in the closed position of the cover. In addition, the cover has a torsion spring associated with it which rotates it to an open position when the locking member is pushed downwardly against its biasing spring.
