A roll holder is for a label roll of linerless labels wound in a crosswise manner. The roll holder has: a horizontally arranged spindle, which is held by a stand on at least one side, and a rotatable roll mount, which is oriented in parallel with the spindle, and which is mounted on the spindle. The roll mount is mounted on the spindle in a linearly displaceable manner using at least one linear bearing.

A web material dispenser for housing two or more rolls is provided. The web material dispenser includes a housing having a fixed housing portion provided with a first roll support assembly coupled thereto for supporting a first roll of web material. The housing further has a movable housing portion, movable between a closed position and an open position, provided with a second roll support assembly coupled thereto for supporting a second roll of web material. The fixed and movable housing portions defining a housing chamber therebetween when the movable portion is in the closed position, for at least partially enclosing the two or more rolls of web material within the housing chamber. The movable portion is moved to the open position for providing access to the two or more rolls and allowing replacement of at least one of the first and second rolls.

The machine (1) comprises: an unwinding section (3) of parent reels (Ba, Bb) of web material (Na, Nb); a cutting station (13), comprising a plurality of cutting members (201, 203) to divide the web material (Na, Nb) into longitudinal strips (S); a plurality of winding stations (15); in each winding station (15), a guide arm (31) to guide the longitudinal strip (S), adjustable parallel to the rotation axis (C-C) of the winding mandrel (51). The cutting station (13) comprises sensor members (213, 214) to detect the position of the cutting members (201, 203). A control unit (216) is interfaced with the sensor members (213, 214) of the cutting station (13) and the positioning actuators (27), to position the guide arms (31) parallel to the rotation axis (C-C) of the respective winding mandrel (51) as a function of the position of the corresponding cutting member (201, 203).

A web material dispenser for housing two or more rolls is provided. The web material dispenser includes a housing having a fixed housing portion provided with a first roll support assembly coupled thereto for supporting a first roll of web material. The housing further has a movable housing portion, movable between a closed position and an open position, provided with a second roll support assembly coupled thereto for supporting a second roll of web material. The fixed and movable housing portions defining a housing chamber therebetween when the movable portion is in the closed position, for at least partially enclosing the two or more rolls of web material within the housing chamber. The movable portion is moved to the open position for providing access to the two or more rolls and allowing replacement of at least one of the first and second rolls.

A sheet product dispenser for dispensing sheet product from a roll of sheet product is provided. An example sheet product dispenser includes a housing defining an interior space for receiving a first roll of sheet product (170a, 170b) therein, a mandrel (150a, 150b) positioned within the interior space, and a spindle (100) positioned over at least a portion of the mandrel and configured to support the first roll of sheet product for rotation about the mandrel. The spindle comprises abase portion (102) and a nose portion (104) configured to translate relative to one another along a longitudinal axis of the mandrel (150a, 150b). At least a portion of the spindle is configured to translate relative to the mandrel from a first configuration to a second configuration to cause a remainder of the first roll of sheet product (170a, 170b) to deform and enable movement of a dispensing door (186) to enable access to a second roll of sheet product.

According to an aspect of the invention, a roll medium feeding shaft to be inserted into a through hole of a roll medium formed by winding a long recording medium is provided. The roll medium feeding shaft includes a holding member configured to be inserted into the through hole and to be rotated about a rotary axis together with the roll medium, a support part provided to one end of the roll medium feeding shaft and configured to support the holding member in a vertical direction when placed on a horizontal surface, and a shaft provided inside the holding member.

Unwinder of a thin ply product wound on a roll, of the type with automatic switching of the unwinding roll with a spare roll, said unwinder comprising—a first roll-holder assembly equipped with a first unwinding rod for a respective roll, on which the roll is adapted to be supported, and which has an axis of rotation transversal to the direction of movement of the ply unwound from the roll, —a second roll-holder assembly equipped with a second unwinding rod for a respective roll, on which the roll is adapted to be supported, said second rod being parallel to said first unwinding rod of the first roll-holder assembly, said second roll-holder assembly facing said first roll-holder assembly in an unwinding zone, wherein of said two roll-holder assemblies, one assembly holds the unwinding roll and the other assembly holds the spare roll to be switched, —a ply splicing assembly placed above said first and second facing roll-holder assemblies, —a ply accumulation unit to allow automatic switching between a roll being unwound in one said roll-holder assembly and a spare roll provided in the other roll-holder assembly, —a transversal position correction system for the side edges of the plies on the rolls present in said roll-holder assemblies.

Spindles and cover assemblies for dispensing sheet product for use with coreless sheet product rolls. The spindle may include a hollow cylindrical body, which may have an elongated channel in a sidewall; a rod which extends partially out of the body; and a spring disposed within the body in biasing contact with the rod. The rod may include a flexible tab matingly engaged within the channel, permitting the rod to translate within the hollow cylindrical body without falling out. The hollow cylindrical body may have an end with an opening bounded by an inward facing ledge, and the rod may include a radial ledge, such that the rod can translate within the body but cannot fall out due to interference between the inward facing ledge and the radial ledge. The spindle may include a friction hub disposed about and rotatable around the hollow cylindrical body between ends of the body.
