Abstract: A clamping apparatus (3) for holding a workpiece (W) between an upper punching tool (19) and a lower punching tool (21) in a machine (1). A frame (33) attaches the clamping apparatus (3) to the machine (1). The clamping apparatus (3) comprises an upper clamp (61) and a lower clamp (57), the latter pivotably cooperating with the upper clamp (61) in order to secure the workpiece (W). The clamping apparatus (3) also comprises a plate member (51) and rods (49) and (75). These rods (49) and (75) are mounted in the frame (33) in a direction perpendicular to the workpiece (W). The lower end of the rods (49) and (75) are attached to the lower clamp (57) and the upper end of the rods (49) and (75) are attached to the plate member (51). A spring (83) is arranged between the lower clamp (57) and the plate member (51) for the purpose of maintaining the lower clamp (57) and the plate member (51) in horizontal orientation whenever the lower clamp (57) collides with the lower punching tool (21).

Abstract: A horizontal bandsaw machine provided with a detecting means for detecting the cross-sectional length of the workpiece being cut during a cutting operation and an actuating means which is controlled by the detecting means to move either or each of the guide means for guiding the bandsaw blade toward and away from the other.

Abstract: A synthetic filament and a yarn composed thereof wherein the filament comprises at least two different incompatible synthetic linear high polymers, one being distributed as islands in the sea of the other polymer element when seen in cross-section, each island being continuous along the axis of the filament and being characterized by their uniformity in cross-sectional dimension in any cross-section of the filament.

Abstract: This disclosure relates to an indexing feed mechanism for a cutting machine comprising an indexing vise for gripping a workpiece and moving it forward into a cutting position. The mechanism includes a lead screw interengaged with complementary means formed on a stopper means adapted to limit the rearward extent of the stroke of the indexing vise. Rotation of said screw will, therefore, cause translation of said stopper means thereby varying the rearward limit of travel of the indexing vise during its stroke. The lead screw extends from a rotatable shaft and means located at the operating station of the cutting machine are provided for rotating the shaft. The shaft is operably connected to a digital indicator which indicates in digital numerals the predetermined stroke of the indexing vise as a function of the angular position of the shaft.
