A sheet transport apparatus according to an embodiment includes a roller having a surface formed from an elastic material. The roller transports a sheet. A rotation mechanism rotated the roller around an axis of the roller. A twist mechanism selectively twists the roller with respect to the axis. When the roller is twisted and the rotation mechanism rotates the roller, a sheet transported by the roller is transported in a first direction perpendicular to the axis and in a second direction parallel to the axis. When the roller is not twisted and the rotation mechanism rotates the roller, a sheet transported by the roller is transported in the first direction and not in the second direction.

The present invention relates to a method and a device for producing a roll (18) made of a material web (5) of flexible material which is guided via a contact roller (19) of a winder and is wound in the said winder to form a roll (18), wherein the contact roller (19) maintains contact with the roll (18) during winding and the wrap angle () of the material web (5) passing over the contact roller (19), as the former is progressively wound, is maintained throughout at a variable reference value predetermined for each winding. In this way the wrap angle () for the winding can be adapted to the respective composition of the material web (5), which improves the quality of the winding.

There is provided a feed apparatus including a support unit, a feed roller, a swingable arm to support the feed roller, a guide unit, a movable member movable to a retracted position and a protruding position at which the movable member can abut against the sheet supported by the support unit, a driving source, driving transmission units; and a contact-separating mechanism to move the feed roller to a separated position and an abutment position at which the feed roller abuts against the sheet supported by the support unit. In a state in which the movable member is the protruding position and the feed roller is the separated position, a time required to start feeding of the sheet by the feed roller moved from the separated position to the abutment position is longer than a time required to shift the movable member from the protruding position to the retracted position.

A method of continuous processing of flexible glass ribbon having a thickness of no more than 0.35 mm using a glass processing apparatus is provided. The method includes providing the glass processing apparatus having at least three processing zones including a first processing zone, a second processing zone and a third processing zone. The flexible glass ribbon is continuously fed from the first processing zone, through the second processing zone to the third processing zone. Rate of the flexible glass ribbon is controlled through each of the first processing zone, second processing zone and third processing zone using a global control device. The second processing zone has a conveyance path for the flexible glass ribbon through a cutting zone having a radius of curvature of from about 100 inches to about 400 inches.

A sheet conveyance apparatus includes a body portion, an openable portion supported by the body portion and configured to be opened and closed with respect to the body portion, a first movable guide supported by the openable portion and movable to a first position at which a first conveyance path through which a sheet is conveyed is formed between the first movable guide and the openable portion and a second position at which the first path is opened, a second movable guide movably supported by the first movable guide, and an abutment portion provided in the body portion. In a state where the openable portion is closed, the second movable guide abut with the abutment portion and is held on a position to form a second conveyance path through which the sheet is conveyed.
