A material strip collection mechanism coiling fed material strip on a reel includes a vertically positioned reel bracket rotatable about a vertical axis between a first configuration and a second configuration. The mechanism further includes a first arm holding the reel and a second arm each rotatable to drive the reel and coil the material strip on the reel. With the reel bracket in the first configuration, the first arm is in a material strip collection position to allow the material strip to be coiled on each empty reel held by the first arm to form a full reel, while the second arm is in a standby position to allow the full reel held by the second arm to be replaced with a new empty reel.

A paper compartment in which roll paper can be held has an opening positioned along the second axial end of the roll paper and a wall positioned along the first axial end of the roll paper in the axial direction. The paper loading member can be removably installed in the paper compartment through the opening. The paper loading member has a flange and a roll support member that projects from the flange and is inserted into the paper. When roll paper is held in the paper compartment, the paper loading member is installed in the paper compartment with a first side of the flange contacting the first axial end of the paper, and the roll support member is inserted into the roll paper. When the paper loading member is installed in the paper compartment, the first side of the flange faces the opening.

A spindle assembly capable of accommodating paper rolls of varying sizes is provided. The spindle assembly comprises a spindle arm adapted to be connected to a printer mechanism. The spindle arm comprises a first flange surrounding an opening. A spindle is provided for accepting a first paper roll. A first end of the spindle is fixed in the opening of the spindle arm. The spindle comprises a second flange arranged at a second end of the spindle. A sleeve is provided which is adapted to slide over the spindle and attach to the spindle arm for accepting a second paper roll. The second paper roll has a different size than the first paper roll. A printer having such a spindle assembly is provided, as is a method for accommodating different sized paper rolls in a printer.

A winding device is capable of easily moving a flange portion to a position corresponding to a width of a continuous medium. A winding device that winds a print medium, the winding device including a winding shaft, a winding core portion that is provided to be rotatable on the winding shaft and that winds a continuous medium, a first flange portion that is provided on the winding shaft to be movable in an extending direction of the winding shaft and that guides the continuous medium wound around the winding core portion in a width direction of the continuous medium, a flange-side engaging portion capable of moving integrally with the first flange portion, and a flange moving section that includes a cylindrical cam provided with a cam-side engaging portion that engages with the flange-side engaging portion and that moves the first flange portion to a plurality of flange positions.

A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: simultaneously winding a first elongated element and a second elongated element respectively on a first winding support in a first axial position and on a second winding support in a first axial position; simultaneously winding a third elongated element and a fourth elongated element respectively on the first winding support in a second axial position different from the first axial position and on the second winding support in a second axial position different from the first axial position, in which the elongated elements of the second type are the same as each other and different from the elongated elements of the first type.

A winding device is capable of easily moving a flange portion to a position corresponding to a width of a continuous medium. A winding device that winds a print medium, the winding device including a winding shaft, a winding core portion that is provided to be rotatable on the winding shaft and that winds a continuous medium, a first flange portion that is provided on the winding shaft to be movable in an extending direction of the winding shaft and that guides the continuous medium wound around the winding core portion in a width direction of the continuous medium, a flange-side engaging portion capable of moving integrally with the first flange portion, and a flange moving section that includes a cylindrical cam provided with a cam-side engaging portion that engages with the flange-side engaging portion and that moves the first flange portion to a plurality of flange positions.

A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: arranging a first winding support with a first elongated element of a first type wound on the first winding support; arranging a second winding support with a second elongated element of a second type different from the elongated element of the first type wound on the second winding support; arranging a coupling device including a first coupling body and a second coupling body rotatable with respect to one another about a rotation axis; and arranging the first winding support on the first coupling body and the second winding support on the second coupling body.

A winding device includes a winding shaft that rotates and winds a print medium conveyed from a printing device having a conveyance roller that conveys the print medium, a gear, and a motor driving the conveyance roller and the gear. The winding device also includes a power transfer mechanism to connect to the gear and transfer power to the motor, and a lever disposed between the winding shaft and the conveyance roller in a conveyance path in a configuration in which the winding device is connected to the printing device. The lever may be moved between a first position in which the print medium bends and a second position in which the print medium bends at a shallower angle than at the first position.
