    摘要： A controller causes a laser beam to move over a strip electrode along a predetermined path thereby cutting the strip electrode into a tab shape. The predetermined path includes a first path, a second path, and a third path. The first path extends from a first position to a second position. The second position is positioned further outside in a width direction perpendicular to the conveyance direction and in the conveyance direction than the first position. The second path extends from the second position to a third position. The third position is positioned in a direction opposite the conveyance direction with respect to the second position. The third path extends from the third position to a fourth position.

    摘要： Provided is a machine tool line configured to simplify and reduce the size of the apparatus. The machine tool line includes a plurality of work tables (21), a temporary holder unit (22) for a workpiece (W), and a control unit. The plurality of work tables (21) are individually movable along the direction of conveyance and have a common area (E12) in which a moving range (23) of a work table (21) overlaps with a moving range (23) of an adjacent work table (21). The temporary holder unit (22) is capable of holding the workpiece (W) positioned in the common area (E12). The control unit moves one work table (21) placed with a workpiece (W) thereon to the common area (E12), temporarily holds the workpiece (W) with use of the temporary holder unit (22), executes retreating of the one work table (21) from the common area (E12) and moving the other work table (21) to the common area (E12), places the workpiece (W) onto the other work table (21), and moves it to a second workpiece-processing position (P).

    摘要： A grinding machine includes a pair of workpiece support devices (12, 13), which clamp and rotate a workpiece (W), on a bed (11). A pair of saddles (14) is provided on the bed (11) in such a way as to be movable along the rotational axis of the workpiece (W). Grindstone heads (16) provided with rotating grindstones (16c) and drive mechanisms (16d) are supported on the saddles (14) in such a way as to be movable in a direction that perpendicularly intersects the movement direction of the saddles (14). There is provided a partition structure (20) which consists of a fixed cover (21) and a extendable cover (22), and serves to partition a machining region (T) for the purpose of sealing off the same so that the clamping portions (12a, 13a) and the rotating grindstones (16c) of both of the workpiece support devices (12, 13) will be located inside the machining region (T), and that bearing sections (12b, 13b) and driving sections (12c, 13c) of both of the workpiece support devices (12, 13), as well as bearing sections (16b) and driving sections (16d) of both of the grindstone heads (16), will be located outside the machining region (T).

    摘要： A web conveying device (100; 200) includes: a chain (7) engaging with a sprocket (6) and driven in a conveying direction (A) of a web (1); and a web guiding member (10) having a front edge (1a) of the web (1) threaded thereinto and driven by the chain (7) to guide the web (1) into a gap. Cam roller members (32) are provided at both ends of the web guiding member (10) and are abutted on a cam member (34). This moves a web pressing member (20; 120) away from an outer periphery (5f), to allow the web pressing member (10) to be inserted into the enlarged gap without interference.

    摘要： Provided is a bed (10) used for a grinding machine (1). The bed has a bed front part (11) on which a workpiece support device (20) is mounted and a bed rear part (15) on which a grinding wheel stand (30) is mounted. An upper portion (12) of the bed front part (11 ) protrudes further to both of the left and the right than a lower portion (13) . A front installation section (17a) is provided in the lower portion (13), and in the bed rear part (15), two rear installation sections (17b) are provided spaced apart from each other in the left-right direction. In this configuration, resonant vibration of the bed (10) due to the vibration of the grinding wheel stand (30) can be suppressed.
