Abstract
A machine for the manufacture of a single-face corrugated board web comprises a pressing device for pressing a liner web against a paper web provided with a corrugation. This pressing device has a pressing belt, of which the tension over its width is individually adjustable in that it is guided along a plurality of tensioning devices which are independent of each other and arranged one beside the other.
Claims20
A machine for the manufacture of an at least single-face corrugated board web (46) comprising
- two fluted rolls (2, 3) for producing a corrugation (41) on a paper web (40),
- a gluing device (13) for applying glue to the peaks (42) of the corrugations (41) of the corrugated paper web (40),
- a pressing device (16) for pressing a liner web (43) on the glue on the peaks (42) of the corrugated paper web (40), which rests on one of the fluted rolls (3) along a pressing zone (45), the pressing device (16) having an endless pressing belt (19), which is guided via a deflection pulley (17) and a further pulley (18, 18') and which is pressed against the fluted roll (3) along the pressing zone (45), and the pressing device (16) having a plurality of tensioning devices for the pressing belt (19),
- wherein over the entire width (d) of the pressing belt (19), the pressing device (16) has a plurality of tensioning devices,
- wherein the pressing belt (19) is guided along a plurality of tensioning pulleys (25), which are movable at right angles to an axis (29) of said tensioning pulleys,
- wherein the tensioning pulleys (25) are moveably supported on a common stationary pulley carrier (23),
- wherein the tensioning pulleys (25) are movable out of the pressing zone (45) about in parallel to the run-off direction (28) of the corrugated board web (46), and
- wherein supporting rings (24) are displaceably supported on the pulley carrier (23), the tensioning pulleys (25) being rotatably supported on the supporting rings (24).
A machine for the manufacture of an at least single-face corrugated board web (46) comprising
- two fluted rolls (2, 3) for producing a corrugation (41) on a paper web (40),
- a gluing device (13) for applying glue to the peaks (42) of the corrugations (41) of the corrugated paper web (40),
- a pressing device (16) for pressing a liner web (43) on the glue on the peaks (42) of the corrugated paper web (40), which rests on one of the fluted rolls (3) along a pressing zone (45), the pressing device (16) having an endless pressing belt (19), which is guided via a deflection pulley (17) and a further pulley (18, 18') and which is pressed against the fluted roll (3) along the pressing zone (45), and the pressing device (16) having a plurality of tensioning devices for the pressing belt (19),
- wherein over the entire width (d) of the pressing belt (19), the pressing device (16) has a plurality of tensioning devices,
- wherein the pressing belt (19) is guided along a plurality of tensioning pulleys (25), which are movable at right angles to their axis (29),
- wherein the tensioning pulleys (25) are movably supported on a common stationary pulley carrier (23), and
- wherein the tensioning pulleys (25) are movable out of the pressing zone (45) about in parallel to the run-off direction (28) of the corrugated board web (46),
- wherein on the pulley carrier (23), supporting rings (24) are pivotably lodged, on which the tensioning pulleys (25) are rotatably supported.
A machine according to clam 13, wherein the tensioning drive (35) is formed by at least one pressure-medium-actuable pressure pad (36).
