| 20110226108 | CUTTING AND EXPANDING DEVICE - The invention relates to a cutting and expanding device for cutting a web of packaging material that is fed to the device via a web inlet into a plurality of individual webs that are conveyed away from the device at a web outlet and spaced apart from one another. | 09-22-2011 |
| 20120055305 | ROLLER-TYPE COMPRESSION-INCISION-CUTTING UNIT - A roller-type compression-incision-cutting unit for packaging material webs comprises: a motor-driven roller ( | 03-08-2012 |
| 083436400 | Plural independent rollers for feed of plural distinct work | 1 |
| 20140360330 | FEED UNIT FOR AN AUTOMATIC SAW CUTTING MACHINE FOR CUTTING TUBES IN DOUBLE-TUBE CUTTING MODE - The feed unit comprises: a first pair of motor-driven lower rollers for moving first tubes forward along a first feed axis; a second pair of motor-driven lower rollers for moving second tubes forward along a second feed axis parallel to the first one; a first pair of upper rollers for urging the first tubes against the first pair of lower rollers; a second pair of upper rollers for urging the second tubes against the second pair of lower rollers; a plurality of first side rollers for retaining laterally the first tubes; and a plurality of second side rollers for retaining laterally the second tubes. The upstream rollers of the first pair of lower rollers and of the second pair of lower rollers are rotatably mounted about a first transverse axis of rotation inclined by an angle (α) to the horizontal. The downstream rollers of the first pair of lower rollers and of the second pair of lower rollers are rotatably mounted about a second transverse axis of rotation parallel to the first one. The upstream rollers of the first pair of upper rollers and of the second pair of upper rollers are rotatably mounted about a third transverse axis of rotation parallel to the first one. The downstream rollers of the first pair of upper rollers and of the second pair of upper rollers are rotatably mounted about a fourth transverse axis of rotation parallel to the first one. Each upper roller is adapted to be moved towards a respective lower roller to clamp a respective tube against the lower roller. The feed unit further comprises a separating element movable between a rest position, in which it is not interposed between the first and second tubes, whereby the first and second tubes are in contact with each other, and a working position, in which it is interposed between the first and second tubes thus preventing these tubes from being in contact with each other. | 12-11-2014 |

| 20090282961 | Tape dispenser with cutter - A dispenser for dispensing material includes a dispenser housing having a material track therein. A dispenser/cutter mechanism contained within the housing includes a trigger handle for activating the dispenser/cutter mechanism. The trigger handle is spring-biased to a non-compressed position, and is shiftable to a tape-cutting position and to a compressed position. A dispensing roller is activated by the trigger handle. A dispensing pawl is operatively located between the trigger handle and the dispenser roller, and the material is trained over the dispenser roller and is moved thereover by the action of the trigger handle. An anti-rebound pawl holds the dispensing roller in a fixed position when the trigger handle is moved to its compressed position. A cam-activated cutting blade is activated by the trigger handle when the trigger handle is moved to its tape-cutting position. | 11-19-2009 |
| 20090288535 | ELECTRIC CLING FILM CUTTER - An electric cling film cutter includes a base provided with a positioning frame, an auxiliary rotating rod and a driving device including a motor and a driving wheel unit. The base is assembled with a delivery wheel having its surface disposed with elongate flutes and plural guide grooves and one side provided with a driven rotating wheel engaged with the driving wheel unit. A cutter positioned before the delivery wheel contains a frame plate, a motor, a belt and a cutter base. The frame plate is provided with idle wheels parallel to and leaning on the delivery wheel. A stripping guide plate is positioned under the delivery wheel, having its upper end formed with plural protruding parting members respectively aligned to the guide grooves on the delivery wheel for pushing the cling film delivered to separate from the surface of the delivery wheel, convenient and safe in use. | 11-26-2009 |
| 20120036975 | DISPENSER - A dispenser for dispensing wiping material through a dispensing opening, includes an outer, first housing for holding at least one roll containing a continuous web of wiping material. The first housing may further hold an inner, cassette including at least a front wall and two side walls, the cassette at least partially enclosing a feeding unit for controlling the dispensing of the web. The feeding unit includes at least a drive roller, a pressure roller and a cutting device, and the web is arranged to be fed from the roll and into the feeding unit. The cassette includes an at least partially removable hatch, which hatch, when opened, is arranged to provide access to the feeding unit. | 02-16-2012 |
| 20120255413 | TRANSFER MECHANISM FOR SHEET MATERIAL DISPENSER - A dispenser for sequentially dispensing rolls of sheet material is described. The dispenser has an automatic transfer mechanism for transferring a reserve roll into a dispensing position once a primary roll has been depleted. The automatic transfer mechanism includes a diameter sensing member and a blocker rotatably coupled to the dispenser housing and biased to rotate in a opposite directions. The diameter sensing member and block cooperate with one another in order to block the reserve roll from contacting a drive roller until the primary roll has been depleted. The reserve roll held in the dispenser by two pivoting arms that are biased to rotate towards the drive roller. | 10-11-2012 |
