The device includes at least a first gripping member and a second gripping member, arranged and controlled so that they extract two winding spindle portions from opposite ends of a log in a longitudinal extraction direction parallel to the axis of the log. The first gripping member and a second gripping member are movable along a log advancing path and extract the two winding spindle portions as they advance along the log advancing path together with the log and the two winding spindle portions.

The machine includes a forming unit with a spindle around which one or more strips of web material are wound; an adhesive applicator to apply an adhesive on at least one surface of at least one strip of web material; a feed path of the at least one strip of web material from the adhesive applicator to the forming unit. The length of the feed path can be modified according to at least one opening parameter.
摘要:
A rewinding machine is described with a winding cradle defined by three rollers and including a fourth winding roller, defining with the first winding roller a cradle in which the web material is pushed by a winding core to the beginning of each winding cycle, to cause severing of the web material without the need for controlled mechanical parts.
摘要:
The rewinding machine comprises: a first winding roller (11) and a second winding roller (13) defining a nip (15) through which said cores are inserted and through which said web material (N) is fed; and at least one pair of motorized engaging members (57), to engage the ends of a winding core and transmit a rotational movement to the core during at least part of the winding cycle of each log. The engaging members and the first and second winding roller are produced and disposed so that the log being formed is in contact with said first and said second winding roller. Moreover, a third winding roller (17) is provided, defining a winding space with said first and said second winding roller, said third winding roller being movable to allow increase and completion of winding of each log in said winding space.

The rewinding machine includes a path for insertion of tubular cores; a winding cradle; a first moving member designed to be in contact with the web material to be wound; a rolling surface forming, with the first moving member, a channel for passage of the tubular cores; and an insertion device to insert the cores in the channel. At the inlet of the insertion channel there is a second moving member, opposed to the first moving member, the core insertion path passing between the first and the second moving members. The two moving members are arranged at a distance such that a core inserted between them is in contact with the second moving member and with the web material entrained around the first moving member.
摘要:
To close the tail end (L) of the web material forming the log (R) there is provided mechanical ply-bonding between the tail end and a portion of the last turn of web material, preferably a portion forming a fold (F) projecting from the log.
摘要:
A rewinding machine for producing logs of web material is described which includes a winding unit; a feed path of the web material towards the winding unit; a severing device to sever the web material upon completion of winding each log; and a glue dispenser to apply a glue to the web material. The machine also includes a diverter member disposed and controlled to temporarily divert the web material towards the glue dispenser.
摘要:
The rewinding machine includes: a winding unit; a feed path of the web material; an insertion path of the winding cores; a separator device to sever the web material upon completion of winding each log. The separator device is disposed and produced to be activated by passage of a winding core.
摘要:
The device for joining at least two plies of paper (V1, V2), in particular tissue paper, comprises a ply-bonding unit (9) and moistening means (11) to moisten at least one of said two plies before joining.
摘要:
The machine comprises in combination: a winding cradle (7); an insertion member (29) to insert winding cores (A, A1) into said cradle; an ejector (39) to eject the logs formed from said cradle (7) causing them to roll on an unloading chute (41); a severing device (55, 53) to sever the web material after ejection of the log from said cradle. Disposed along the unloading chute is an aperture (43) elongated in a direction transverse to the direction in which the log is unloaded along said unloading chute. Moreover, the severing device (53, 55) includes a movable element (55) that is inserted into said aperture (43) to cause severing of the web material between the cradle and the finished log.
