  • Patent number: 11319653
    Abstract: The new device for producing pompons comprises a ring carrier, which holds two winding disks in a holding region, wherein two half-ring-shaped disk halves together form a winding disk. Outside the holding area for the disc halves, the ring carrier has a handle. This handle can be grasped during the entire pompon production without hindering the winding process or the cutting.

  • Patent number: 10106922
    Abstract: A knitting needle having at least one needle tip and a shank on which the knitting can be at least regionally arranged. A gripping region is arranged on the shank which can be gripped by a user during knitting. The knitting needle narrows along its length from the shank in the direction of the needle tip and is designed in a rounded manner and a droplet-shaped thickening, namely a retrieval droplet, is attached thereto, the latter having a smaller diameter than the shank. The transition between the shank and the narrowed portion and between the narrowed portion and the retrieval droplet is formed without edges and with little frictional resistance. Also included is a method for producing such a knitting needle. In said method, the knitting needle is designed as a circular knitting needle, wherein, during the production the cord is overmoulded with the material of the shank.

  • Patent number: 7997945
    Abstract: The invention relates to a device (10.1) for connecting a web (25), comprising a pair of limbs (11, 12), the first two limb ends (13) being fixed to a support (30) while the remaining two limb ends (14) spring back and produce spring ends (14) for the purpose of connecting a web (25). In order to obtain a simpler and reliable connection, it is proposed that the two spring ends of the pair of limbs (11, 12) are connected to each other by means of a loop (20), the inside of the loop (24) serving to accommodate the web (25). When the web is connected, the loop (20) encompasses the cross section of the web and maintains it between its spring ends (14).

  • Patent number: 7713086
    Abstract: A component (30) is to be attached by means of a plug connector (10) in a hole (53) of a base plate (50). To this end, the plug connector (10) has a shaft (15) with a flat profile. When the plug is inserted in the socket, the shaft end (20) projects out of the hole (53) on the rear side of the circuit board (52). The shaft end (20) is followed by a shaft section (13), broadened relative to the hole width (54), which has an opening (14). By means of the opening (14), the shaft section (13) is split into two legs (11, 12), which are sprung against each another and which hold the shaft (15) in the hole (53) of the circuit board (50) when the plug is inserted in the socket. To improve the holding effect, the two legs (11, 12) are constructed differently one from the other, wherein one leg (11) has a greater longitudinal extension (21) than the other (12). This means that the broadened shaft section (13) splits into a long (11) and a short leg (12).

  • Patent number: 6907647
    Abstract: The invention relates to a ringless eyelet (10?) comprising a plate (11) arranged on the display side (23) of the carrier strip (20), and a tube-shaped collar penetrating the hole in the carrier strip. The hem of the collar of the eyelet element (10?) is supported on the rear side (24) of the carrier strip (20). The aim of the invention is to connect the eyelet to the carrier strip (20) faster and in a more cost-effective manner. In order to achieve this, the free end part of the collar of the eyelet element (10?) is provided with projections (16). An essentially closed ring profile (50), into which the collar projections (16) are integrated, is created when the collar is hemmed. After hemming, pressure points (40) are created on the carrier strip (20) between the collar projections (16) and the abutment surfaces (49) formed by the plate (11), said pressure points reliably holding the carrier strip (20). Said carrier strip (20) extends namely inside (51) the ring profile (50) beyond the pressure points (40).

  • Patent number: 6435219
    Abstract: A woven strip of a zipper half is produced of warp and weft threads. The weft thread is picked in the form of double pick loops. A plastic monofilament forms windings of a closing member row on the woven strip with interlocking heads at one end and winding reversing portions at the other end. During weaving, a main knit thread is guided upwardly between the windings to the upper side of the closing member row to form loops with loop heads that are interlocked by crocheting and form a mesh structure for interlocking the closure member row with the woven strip. Simultaneously, double pick loops of the main knit thread are formed and are interlaced during weaving with additional warp threads positioned underneath the closing member row. The main knit thread is used as a weft thread in the woven strip underneath the closing member row.

  • Patent number: 6364753
    Abstract: The invention relates to a method for producing battery terminals comprising different steps, during which a continuous wire (18) is cut (22) into predefined lengths, and then a pin head and point are formed. To this end, a conveyor path (40) is used, at the end of which the pegs (10) fall into a receptacle. In order to accelerate and simplify finishing of the pointed pins (10″), the aftertreatment of the pin points takes place on the conveyor path (40), between the sharpening stage (23) and the collecting receptacle (70), during which unwanted burrs can be removed on another cylinder (60). As a result, already finished pins fall into the receptacle at the end of the conveyor path.

  • Patent number: 5970588
    Abstract: A snap closure with a male part whose male coupling surfaces have an enlarged closing head at a closing neck, with a two-part female part comprising a housing having an insertion hole for the male coupling surfaces, and with two plate-shaped slides which are identical in shape, spring-loaded in opposite directions, project out on opposite sides of the housing by their outer ends which serve for actuation, and can be pressed in against the spring loading in opposite directions relative to one another transverse to the insertion hole, wherein, on the one hand, the two slides have, in their mutual joint region, complementing closing parts for a common locking profile which engages behind the inserted closing head of the male part when coupling, and, on the other hand, are cut out and have a common release profile for decoupling the closing head, wherein each of the two slides which are made of elastic material are provided at their inner ends with a longitudinally elastic spring portion formed integral with the

  • Patent number: 5957362
    Abstract: An apparatus for attaching rivets, buttons or the like to textiles or the like, having a plunger which performs the riveting stroke and whose upward and downward movement is controlled by the interaction of the top end of the plunger with a cam plate rotationally driven by an electric motor, the apparatus performing a sequence of attachments upon actuation of a switch or the like, the electric motor (39) running at a fixed preset angular velocity being stopped briefly in the top dead-center position of the plunger (24) by a braking device or the like in order to reduce the cycle frequency of the plunger stroke. To this end, the control unit switches off the drive motor (39) in the top dead-center position of the plunger for a preprogrammed time and switches it on again after the preprogrammed waiting time has expired and actuates a brake in particular during the waiting time.

  • Patent number: 5908148
    Abstract: A device for fitting articles including rivets, buttons and the like, to a fabric, comprising a lower tool serving as an abutment for an article, and a ram executing a riveting stroke. A lower end of the ram joins with an upper tool for impinging upon an upper portion of the article and for urging the article against the lower tool upon execution of the riveting stroke. A rotatably driven cam disc urges an upper end of the ram for controlling travel movement of the ram. A clamp is carried by the bottom end of the ram for movement in synchronism with the ram. For finger protection, the device is operative to stop the clamp in a position spaced from the lower tool during a first lowering movement.
