摘要:
A method for producing logs (L1, L2) of web material (N) wound around tubular cores wherein the tubular core (A1-A4) is equipped with glue to secure the initial end of the web material and allow winding. Part of the glue applied to the tubular core is transferred to the web material (N) before it is severed upon termination of winding the log, to seal the final free end of the formed log.

摘要:
A device for distributing glue on an end edge of a log, on a log or on a core for logs comprising a feed surface (16) of logs or cores (15) towards a glue distribution area, wherein the device comprises a container (13) containing glue (12), wherein disposed inside the container (13) is a fixed blade (18) with one free end (22) facing upwards at the level of an interrupted section (19) of the feed surface (16) on which the logs or cores (15) travel, one behind another, the fixed blade (18) being associated with a plate (27) movable from the bottom upwards, and vice versa, which conveys the glue (12) to the level of an upper free end (22) of the fixed blade (18), discharges it on the free end (22) and returns towards the bottom of the container (13), the moving plate (27) having, at an upper end thereof, an area to collect glue (28, 29) in the container (13) and to discharge glue on the fixed blade when it is taken to the level of the upper end (22) of the fixed blade (18).

摘要:
A device for re-reeling and forming a roll of paper in a re-reeling machine comprising, on a frame, three rollers (16, 17, 18) having mutually parallel axes that are perpendicular to the direction of feed of the paper (11), in which two winding rollers, a bottom one (17) and a top one (16), supported on the frame, co-operate with a third roller (18) that maintains a certain pressure on a roll of paper or log being formed, where the third roller (18) is carried by a pair of arms (22) which can oscillate with respect to the frame, the paper (11) that is being wound passing over one of the two rollers, and the finished roll or log (19) coming out of an outlet aperture or gap (30) identified between the bottom roller and the third roller, and the cores (12) for said rolls being fed, one after another, by a pusher conveyor (15) and being introduced into a channel (24) made underneath the top roller (16) by an oscillating pusher (27, 35) which co-operates for inserting the core (12), possibly provided with adhesive, there also being provided an arrest element (32, 132) for at least partial arrest of the paper (11) upstream of the point of insertion of the core (12).
摘要:
The rewinding machine for the production of rolls of weblike material comprises: a winding-up system (1, 3, 5) for winding up the weblike material on winding-up mandrels (M), and an extractor (23) for separating the mandrels from the respective rolls formed thereon. A device for washing the mandrels is also provided.

摘要:
A device for distributing glue on an end edge of a log, a log or a core for a log, comprising a feeder (26) of logs (19, 19null) or cores (25) towards a glue dispensing unit, in which the glue dispensing unit comprises a tank (15) containing glue (20) in which is placed a thread (12) wound in a loop on at least two end pulleys (13), at least one of which is commanded in continuous rotation by a gear motor (14), the thread (12) having a lower branch which lifts the glue and an upper branch which releases the glue on an end edge (18, 18null) of a log (19, 19null), a log (19, 19null) or a core (25) for a log.
摘要:
An apparatus for applying an adhesive coated tape on a core mounted on a mandrel, includes a mounting frame having mounted thereon an adhesive tape supply roller, a rewind roller, an idler roller mounted between the supply and rewind rollers such that the adhesive tape on the idler roller can be sandwiched between the idler roller and mandrel and transferred to the mandrel with the carrier layer being wound on the rewind roller, a motor for rotating the rewind roller, and a knife assembly pivotally mounted thereon adjacent the idler roller for cutting the adhesive layer extending between the supply roller and mandrel after the adhesive layer has been transferred to the mandrel; two link arms pivotally connecting the mounting frame about a pivot shaft secured to a main frame; a piston-cylinder assembly for pivotally moving the mounting frame about the link arms and relative to the mandrel such that the adhesive tape around the idler roller can be transferred to the mandrel; and a cam plate for pivotally moving the knife assembly to cause the adhesive layer which sticks to the knife to disengage from the knife assembly and fall onto the carrier layer.
