摘要： An assembly for cutting foam, nonwoven, rubber, and composite products has a guide having a longitudinally extending guide edge formed with a longitudinally extending and outwardly open groove. A longitudinally extending row of cutting elements extends along the guide edge, and element each has an entrainment dog projecting inward into the groove, a support riding on the guide edge and having sides each formed with a pair of longitudinally spaced and outwardly open recesses, a base outward of the support, and a wedge-section cutting tooth forming a cutting edge outside the base and having a pair of longitudinally extending flanks converging at the cutting edge. Coupling links extend between and have ends set in the recesses of adjacent cutting elements. Pivot pins extend through the ends of the links and through the supports at the bases. The base is of a maximum width greater than a width of the assembly at the pins.

摘要： A slotted tube shaft carrying a blade head of a blade twister rotates in a slotted, stationary bearing housing for an endless band-shaped cutting or sawing element supported by two axially spaced subassemblies each having C-shaped, axially spaced, and slotted inner and outer bearing washers radially between the slotted stationary bearing housing and the slotted tube shaft. The inner and outer washers are fixed in the stationary bearing housing against rotation relative thereto with slots of the stationary bearing housing and washers radially aligned with one another. Respective sets of at least three roller bearings centered on and angularly distributed about the axis and fixed against angular movement between each of the inner washers and the respective outer washer. Each roller bearing radially outwardly engages the slotted stationary bearing housing and radially inwardly engages the tube shaft.

摘要： A needle grab for handling workpieces has a bar-shaped longitudinally elongated housing having a longitudinally extending face and first and second longitudinally spaced guides defining respective first and second transverse directions that cross each other. First and second holders are transversely slidable in the first and second guides in the respective directions and carry respective first and second sets of at least three first and second grab needles movable with the respective holders relative to the face between a release position recessed behind the face and a gripping position projecting from the face in the first and second directions. A single servomotor is mounted on the housing and is connected via a gear train to both of the holders for synchronously moving same to displace the first and second sets of needles synchronously in the respective first and second directions.
