摘要:
Apparatus for moving logs (2) within cutting-off machines. The apparatus includes a platform (1) with one or more longitudinal channels (10) inside which the logs to be cut are disposed, and a pusher device (3) acting in correspondence of the platform (1) and intended for acting on the back of the logs (2) to push them, along respective guide channels (10), toward a cutting device (4) disposed downstream. The apparatus includes a clamping device (5) disposed intermediate between the pusher device (3) and the cutting device (4) and intended for engaging the logs (2) which are pushed along the channels (10) of platform (1) by the pusher device (3) and driving them along up to the cutting device (4).
摘要:
Apparatus for trimming paper rolls or logs (2) including: a section for the entry of the logs (2) to be trimmed; a section for the exit of the trimmed logs (2′); a station with cutting device (6) for trimming the logs (2); a device (3) for moving the logs (2, 2′) between the entry section, the cutting station and the exit section; a device (4), associated with the log-moving device (3), for retaining the logs when subjected to movement.

Apparatus for trimming paper rolls or logs (2) characterized in that it comprises: a section for the entry of the logs (2) to be trimmed; a section for the exit of the trimmed logs (2′); a station with cutting means (6) for trimming the logs (2); means (3) for moving the logs (2, 2′) between the entry section, the cutting station and the exit section; means (4), associated with the log-moving means (3), for retaining the logs when subjected to movement.
摘要:
A method for producing logs of paper comprises: feeding a continuous paper web along a fixed path; transversely perforating the paper web such that the paper can be subdivided into various lengths and detached by tearing; feeding tubes such that a preset number of sheets are wound onto said tube to form a log, the tubes being guided in a tube-guiding channel extending between a tube-feeding station and a log-forming station, the channel being delimited in part by a fixed guide and in part by a roller for feeding the paper; and applying glue within the channel such that the last sheet is glued to the log being formed and the paper web is glued to the next tube.
摘要:
Method for producing cardboard tubes by winding a plurality of ribbons (U, L) onto a spindle (1), a preset number of the ribbons (U, L) being glued in correspondence of the lower or radial inner surface thereof, characterized in that a predetermined amount of supplementary quick setting glue is applied on the lower surface of the last ribbon (U) destined to be wound on the spindle (1), in proximity to at least a longitudinal edge (BU) of the ribbon (U) forming a corresponding stripe of quick setting glue (G) astride of a section (ST) of the same ribbon interested or intersected by a subsequent cutting action executed downstream of the spindle (1).
摘要:
Apparatus for causing paper webs to tear off within rewinding machines, the web (2) being provided, at regular intervals, with transverse perforation which subdivide the web into sheets joined to each other but able to be separated in correspondence of said perforation lines, the apparatus comprising a device to cause the tearing of the web (2) upon the passage of a perforation line (p) which separates the last sheet of a log (RO) in the course of formation from the first sheet of the next log to be formed, characterized in that the tearing device is a pneumatic type device (SP) able to direct a jet of compressed air toward the line (p).
