A machine for unwinding and rewinding a covering tape (800) includes a first support shaft to coaxially receive a reel of covering tape, a second support shaft, parallel to and distanced from the first support shaft, which is adapted to coaxially receive a tubular support, a motor adapted to put the second support shaft in rotation around its own axis, a plurality of contrast rollers arranged around the second support shaft and oriented parallel thereto, and a movement apparatus adapted to move the contrast rollers towards and away from the axis of the second support shaft.

The present application relates to rolled good feeding device and method. Material feeding devices and methods are provided for conveying material from material rolls. The material roll may be adjusted in the longitudinal direction during the feeding process by a rectifying frame to aid in maintaining alignment during the unrolling. Tension of the unrolled material may be monitored and unrolling speeds of the feeding device can be adjusted to maintain tension of the material within a range for that material. Aspects also contemplate elements to feed multiple rolled materials simultaneously for subsequent processing in combination as layered materials.

A roll sheet with a continuous sheet wound in a roll form is rotated in a forward direction to supply the sheet to a printing unit. A sensor whose output is changed in accordance with a distance between the sensor and the sheet is used. A rotation direction of the roll sheet is switched from an opposite direction to the forward direction on the basis of the output of the sensor during rotation of the roll sheet in the opposite direction.

A frame for cradling a rolled surface covering during installation onto a ground surface, including first and second spaced-apart end panels, a surface covering support base extending between the first and second spaced-apart panels and adapted for holding the rolled surface covering during installation. At least one lower roller extends along the support base between the first and second spaced-apart end panels at a level above the support base, and at least one upper roller extends along the support base between the first and second spaced-apart end panels at a level above the support base and is vertically spaced-apart from the at least one lower roller. The space defines a gap extending along a length of the at least one lower roller and the at least one upper roller through which a free end of the rolled surface covering is extended during installation onto the ground surface.

Winding apparatuses for winding sheet material and related methods are disclosed herein. The winding apparatuses can include a set of winding drive rollers. Each drive roller of the winding drive rollers can have drive wheels spaced apart along the respective drive roller with a winding zone between the winding drive rollers. The winding apparatus can also include a feed system positioned before the set of the winding drive rollers for moving sheet material along a travel path in a machine direction into the winding zone.

The rewinding machine includes a first winding cradle formed between a first winding roller, a second winding roller and a third winding roller. The first winding roller and the second winding roller define a nip through which there pass the winding cores with the web material being wound around them. The rewinding machine also includes a feed path of the winding cores that pass between the first winding roller and the third winding roller. A second winding cradle is formed between the first winding roller, the second winding roller and a fourth winding roller. The rewinding machine also includes a rolling surface extending around the first winding roller and defining a feed channel of the winding cores.

An apparatus and method for supporting sheet material, comprising a frame including a first arm and a second arm, the second arm in communication with the first arm to support a roll of the sheet material there-between, and a drive roller for transporting the sheet material from the roll. The first arm and the second arm automatically resize the frame corresponding to the dimensions of the roll of the sheet material to provide constant tension in the roll of sheet material by controlling a position of the roll of the sheet material.
