Abstract
Abstract One-sided corrugated board machine having at least two pair of corrugated rollers, a lower pair and an upper pair, wherein each pair of lower and upper corrugated rollers are supported on separate lateral, pivotable and fixable bearing brackets. A movable glue-applying device and clamping roller are provided such that they can be moved away from the pivoting path of the corrugated rollers. When it is desired to change the rollers of a single pair, one for another, the glue-applying device and the clamping roller are moved away from the pivoting path and the corrugated rollers are pivoted so as to change each pair of rollers one for another without having to rethread the paper tracks.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
225 words
A one-sided corrugated board machine having at least two pairs of corrugated rollers each pair having a rotational axis; a glue-applying device; a movable clamping roller; guide units for the paper sheet to be corrugated and for the smooth cover sheet; as well as guide units for the emerging one-sided corrugated board, said corrugated board machine comprising: an upper pair of corrugated rollers supported on lateral, pivotable, and fixable bearing means for pivoting said pair of rollers around the rotational axis to locate one of said pair of rollers from a work position to a rest position and the other of said pair of rollers from said rest position to said work position; a lower pair of corrugated rollers supported on lateral, pivotable, and fixable bearing means for pivoting said pair of rollers around the rotational axis to locate one of said pair of rollers from a work position to a rest position and the other of said pair of rollers from said rest position to said work position to form a corrugating nip with the corrugating roller of said upper pair positioned in said work position; and movable glue-applying means for positioning said glue-applying device away from the pivoting path of said corrugated rollers for changing said rollers from one position to another without having to rethread the paper sheets in the guide units.
Claim 2
Dependent Claim
225 words
A one-sided corrugated board machine having at least two pairs of corrugated rollers each pair having a rotational axis; a glue-applying device; a movable clamping roller; guide units for the paper sheet to be corrugated and for the smooth cover sheet; as well as guide units for the emerging one-sided corrugated board, said corrugated board machine comprising: an upper pair of corrugated rollers supported on lateral, pivotable, and fixable bearing means for pivoting said pair of rollers around the rotational axis to locate one of said pair of rollers from a work position to a rest position and the other of said pair of rollers from said rest position to said work position; a lower pair of corrugated rollers supported on lateral, pivotable, and fixable bearing means for pivoting said pair of rollers around the rotational axis to locate one of said pair of rollers from a work position to a rest position and the other of said pair of rollers from said rest position to said work position to form a corrugating nip with the corrugating roller of said upper pair positioned in said work position; and movable glue-applying means for positioning said glue-applying device away from the pivoting path of said corrugated rollers for changing said rollers from one position to another without having to rethread the paper sheets in the guide units.
