摘要:
An automatic machine (1) for providing corrugated sheet-like elements, comprising means (3) for the continuous corrugation of a ribbon (5) in motion in a longitudinal direction, wherein the corrugation means (3) comprise an upper conveyor (7) and a lower conveyor (9); the upper conveyor (7) comprises a plurality of upper abutment elements (70) that are extended substantially transversely to the longitudinal direction of motion of the ribbon (5); the lower conveyor (9) comprises a plurality of lower abutment elements (90) that are extended substantially transversely to the longitudinal direction of motion of the ribbon (5); the upper abutment elements (70) are intercalated between the lower abutment elements (90) in a work area (11); the upper abutment elements (70) each comprise a flap (71, 91), which has, in the end (73) adapted to make contact with the ribbon (5), at least one portion that comprises grip means (75, 77, 770).
摘要:
An automatic machine (1) for providing corrugated sheet-like elements, comprising means (3) for the continuous corrugation of a band (5) that moves in a longitudinal direction, where the corrugation means (3) comprising an upper conveyor (7) and a lower conveyor (9). The upper conveyor (7) comprises a plurality of upper abutment elements (70) that extend transversely to the longitudinal direction of motion of the ribbon (5). The lower conveyor (9) comprises a plurality of lower abutment elements (90) that extend transversely to the longitudinal direction of motion of the band (5). The upper abutment elements (70) are interleaved with the lower abutment elements (90) in a work region (11). The machine further comprising: - anticipating means (13) for anticipating, at the inlet to the work region (11), the inclination of the upper abutment elements (70) with respect to a direction that is perpendicular to the tangent of the path followed by the upper conveyor (7), and - delay means (15), for delaying, in output from the work region (11), the inclination of the upper abutment elements (70) with respect to a direction that is perpendicular to the tangent of the path followed by the upper conveyor (7).
摘要:
An automatic machine (1) for manufacturing shaped plate-like elements, particularly for packagings, thermal and acoustic insulations, comprises a supporting frame (2), on which shaping means (10) are provided, for the continuous shaping of first longitudinally moving ribbon (5). The shaping means (10) comprise a roller with radial fins (11), constituted by a core (12), from which wings (13) protrude. The roller with radial fins (11) in practice mates by meshing with insertion bars (20), which are arranged according to a cylindrical configuration and are supported at their axial ends by bell-shaped flanges (25), which are supported rotatably, by means of the interposition of bearings (26), by a rotationally fixed shaft (27). In order to optimize the insertion of the first ribbon (5) and prevent interference between the wings and the insertion bars, motion means are provided for the radial translational motion of the bars (20).
摘要:
An automatic machine (1) for manufacturing shaped plate-like elements, particularly for packagings, thermal and acoustic insulations, and the like, which has the particularity that it comprises shaping means (10) for the continuous shaping of a first longitudinally moving ribbon (5), arrangement means (51, 52) for arranging a second ribbon (58) laterally adjacent to the shaped ribbon in output from the shaping means for the continuous shaping of a first ribbon, and coupling means (60) for coupling, at least in discrete regions, the first and second ribbons (5, 55).
