| 20100331160 | APPARATUS FOR PRODUCING CORRUGATED BOARD - An apparatus is provided for producing longitudinally corrugated product. The apparatus includes a guide roll for guiding a web of medium material, wherein at least a portion of the guide roll is adapted to be arranged at an angle relative to another portion of the guide roll. The apparatus further includes a plurality of flute forming bars oriented generally along a longitudinal axis of the web to define a first corrugating labyrinth effective to longitudinally corrugate the web to an intermediate geometry. The apparatus further includes a pair of corrugating rollers that cooperate to define, at a nip therebetween, a second corrugating labyrinth effective to longitudinally corrugate the web to a substantially final geometry. The apparatus further includes a web travel pathway for the web that follows a path around a portion of the guide roll, through the first corrugating labyrinth, and through the second corrugating labyrinth. | 12-30-2010 |
| 20110218092 | SHEET FOLDING MECHANISM, SHEET POST-PROCESSING APPARATUS AND METHOD THEREOF - Certain embodiments provide a sheet folding mechanism including: a folding unit; a shaft; a pair of discharge rollers provided on the shaft; a pair of pinch rollers; a pair of clutches configured to transmit a rotational force only in the reverse direction; a pair of corrugation rollers, each of the corrugation rollers having a cam surface including a first diameter portion and a second diameter portion on an outer peripheral surface thereof, and an eccentric bearing to be fixed to each of the pair of clutches; a lock member configured to prevent the pair of corrugation rollers from idling; a drive unit configured to rotate the shaft; and a controller configured to cause the corrugation rollers to apply corrugation on the sheet bundle using any one of the first diameter portions and the second diameter portions according to the number of sheets in the sheet bundle. | 09-08-2011 |
| 20160002000 | SHEET PROCESSING DEVICE AND IMAGE FORMING APPARATUS - According to an aspect of the present invention, there is provided a sheet processing device including a first teeth portion, a second teeth portion that clamps and binds a sheet bundle with the first teeth portion, a first support portion supporting the first teeth portion, a shaft, and a second support portion supporting the second teeth portion. The second support portion includes first and second arm members integrally supported to be capable of swinging around the shaft between a binding position in which the second teeth portion clamps and binds the sheet bundle with the first teeth portion and a standby position in which the second teeth portion is apart from the first teeth portion. The second arm member is provided over the first arm member so as to cover a part of the first arm member. | 01-07-2016 |
| 20160075532 | Method And Device For Deforming A Profiled Shape Of A Material Web Into A Regularly Undulating And/Or Periodic Profile - A method for transforming a profile form, in particular a longitudinal profile form of a material web in a regularly corrugated and/or periodic profile structure, wherein the material web comprises as material paper and/or plastic and/or plastic sheeting and/or heat-insulating material except for materials with metal/metallic and/or heat-conductive components, using one or more moving transforming means with which the material web is brought into positive engagement, wherein after the engagement of the transforming means the material web profiled as a consequence is brought in positive engagement with one or several adjustment means profiled in a complementary manner that are moved in such a manner relative to the transforming means that the profile structure formed by the transforming means is subjected for adjusting, changing or maintaining its accuracy to size to a possible subsequent fine adjustment and/or correction. | 03-17-2016 |
