  • Patent number: 5211320
    Abstract: The present invention pertains to a device for bending over a fabric, especially pockets to be sewn onto a fabric layer, with plates that are arranged in essentially parallel planes and cooperate with one another, a fabric support plate and bending plates, and with a pressing member that can be placed over the fabric, as well as with guide surfaces for the bending area of the fabric. It accomplishes the task of designing the device such that reliable and accurate bending of the fabric is made possible in a relatively simple manner, with only minor effort for adjustment. To achieve this, it has a pressing member (4), whose outer contour extends beyond the outer contour of the fabric support plate (1) in the area of the bending edges of the fabric support plate (1), and which has, at least in its edge zone, an elastically deformable holding member (15) for the fabric (2), which forms a guide surface for the fabric (2) in its bending area after the pressing member (4) has been placed over the fabric (2).

  • Patent number: 4570560
    Abstract: A stop motion device for stopping the motion of a sewing, embroidering or tufting machine, comprises a pivotally mounted sensing lever having a sensing arm for receiving threads used by the machine. The sensing lever is also engaged with a switch for deactivating the machine when the lever is pivoted into a position to disengage the switch. A fixedly mounted guide is provided for guiding the threads at a location spaced from the sensing arm in the feed direction for the threads. Either the sensing arm or the guide includes one bore for guiding all the threads while the other includes two offset bores each for receiving at least one thread. The offset bores are offset perpendicularly with respect to the feed direction and with respect to the other single bore. When one of the threads breaks, the tension of the remaining threads causes the sensing lever to pivot and thus activates the switch to stop the machine.

  • Patent number: 4471706
    Abstract: A device for feeding a strip of material into a sewing machine so that it can be sewed onto a cut fabric which is fed over a base plate includes a stop which is positionable in the feed path of the strip of material and which control the operation of the sewing machine so that the strip will not be fed unless it is aligned with the associated workpiece and guided past a reciprocating needle.

  • Patent number: 4284020
    Abstract: A thread monitor particularly for a sewing machine having a needle, the monitor comprising a control device operable for stopping the operation of the machine, a thread feeler engageable with the thread supplied to the needle, and a bracket mounting the feeler for movement between a retracted position with respect to the control device and an operative position for actuating the control device for stopping the operation of the machine. The feeler is biased toward its operative position, the bias being greater than the frictional force present between the feeler and its mounting as the machine vibrates during the operation thereof but less than the frictional force present between the feeler and its mounting when the machine is not in operation, so that, upon thread breakage when the machine is in operation, the feeler will move to its operative position for stopping the operation of the machine and, when the machine is not in operation, the feeler remains in retracted position.
