Abstract: The system for machining the bottom of skis comprises a machine frame, in which a ski is stationary supported by roller carriers. The machining is performed by machining tools on a carriage, which extends throughout under the ski. During the machining, the carrier rollers that are alternately arranged behind each other, take over the support of the ski. There are always so many carrier rollers directly under the ski that its bottom remains in a stationary position.

Abstract: The device for the assembly of pocket spring strings includes a rack, on which a drum having receptacles for pocket spring strings is rotatably supported. An operator manually places the pocket spring strings into the receptacles and rotates, or initiates the rotation of, the drum about a predetermined angle, for example 60°. Now, the operator places a further pocket spring string into the subsequent receptacle , and at the same time an adhesive is applied to the advanced pocket spring string. Following a further rotational movement of the drum, the next pocket spring string is inserted, an adhesive is applied to the previously inserted pocket spring string, and at the same time the pocket spring string to which the adhesive was applied and which is now located in front of the assembly device is ejected.

Abstract: The spring winding machine (1) comprises a measuring device (25a) with a measuring sensor (27) which is arranged in front of the shaper (11) with respect to the conveyor direction of the wire (13) to be shaped.

Abstract: The device for aligning springs (7) on transport from a spring winding machine to a spring interior assembly automatic machine comprises at least one rotary plate pair (17) which rotates about a rotary axle (B) and is drivably mounted about a rotary axle (A). From a take-over location (X) the springs (7) are individually taken over by a gripper hand (5) of a transport star (1) and, slightly pressed together, are inserted between two rotary plates (17). The springs (7) are aligned by the rotary plates (17) so that at the transfer location (Y) they have the desired rotary angle end position and may be inserted by at least one transfer finger (27) between the belt faces (13) of two transport belts (13).

Abstract: A string (12) of pocketed coil springs (14) is formed by inserting compressed springs between upper and lower plies of a folded, preferably thermally weldable fabric (16). The springs are maintaned in a compressed configuration while a longitudinal seam (54) joins the free edges of the thermally welded fabric (16) together. Subsequently, the compressed springs (14) are allowed to relax into an expanded configuration after which a transverse seam (80) is formed in the fabric (16) between the adjacent springs (14) thereby encapsulating each spring (14) within a fabric pocket (86). The string (12) of pocketed coil springs (14) is advantageously formed without the need for reorienting the springs (14) after being inserted between the plies (24,26) of the fabric (16) and thereby avoiding the disadvantages and complications associated with turning or reorienting the pocketed coil spring (14).

Abstract: A device and method for turning and relaxing compressed springs in pocket sections of a spring pocket row is provided. The device comprises a push rod having a lower limb and a connection rod. A first linear drive pivots the push rod about a vertical axis and the second linear drive raises and lowers the push rod. During a working stroke the first linear drive pivots the push rod so at least one compressed spring is seized and displaced in a pocket section. The push rod is returned to its original position before the spring pocket row is advanced. The process is then repeated.

Abstract: The installation for the transport of helical-shaped wound springs comprises a star turret with gripper hands. The gripper hands consist of two jaws of which at least one is pivotable and is pressable with the force of a tension spring against the second. The spring produced on the winding machine is pressed by the insertion means into the gripper hand and is held firmly by this by the force of the tension spring during the transport and during the heat treatment. For the transfer of the spring to a transport device insertion jaws are pivotably connected to the transport means and push the spring out of the gripper hand, overcoming at least a part of the tension force of the tension spring, into a receiver on the transport device.

Abstract: For measuring the air charge of a plastic component for a low-pressure multicomponent foam system, the gas-charged plastic component is admitted into a measuring chamber. The gas pressure of the plastic component displaces a measuring piston in the measuring chamber and the displacement distance of the piston is a measure of the gas charge.
