The invention relates to a winding machine for winding material webs, in particular foils or films, wherein the winding machine comprises a feeder system with a first belt feeder which, during the winding of the material web around a winding core in a first direction, wraps itself at least partially around the material web. The feeder system comprises a second belt feeder which is suitable for winding the material web in a second direction around the winding core.

A heat treatment apparatus for high-quality graphene synthesis comprises an upper roll chamber, a deposition chamber connected to the upper roll chamber to deposit graphene on a catalytic metal film, and a lower roll chamber mounted on a lower portion of the deposition chamber. The upper roll chamber includes a supply roller and the lower roll chamber includes a lower direction shifting roller shifting a direction of the catalytic metal film supplied from the supply roller. In the deposition chamber, a catalytic metal film at a supply side transferred from the supply roller to the lower direction shifting roller and a catalytic metal film at a discharge side transferred from the lower direction shifting roller to a winding roller are passed, and a heater portion is mounted around the catalytic metal film at the supply side and the catalytic metal film at the discharge side.

A controller includes: an adhesion member position determination unit that determines a position of an adhesion member in a rotation direction of a roll on the basis of the result of detection from an adhesion member detector in a state in which the roll has been rotated by a shaft control unit; and an outer diameter determination unit that determines an outer diameter of the roll in a portion where the adhesion member is positioned, the determination being performed on the basis of the result of detection from an outer diameter detector in a state in which driving of shaft drive sources are controlled by the shaft control unit such that the adhesion member is positioned within a detection range of the outer diameter detector on the basis of the position of the adhesion member determined by the adhesion member position determination unit.

Apparatus for variable width turn-up procedures on a paper processing machine. The apparatus may include a turn-up tape dispenser fixedly attached to a proximal end of a transverse track and movable with the transverse track along the first linear bearing. A movable turn-up tape exit point may be mounted to a second linear bearing. The second linear bearing may be independent of the transverse track or attached to the transverse track. The apparatus may include a brake operable to secure the transverse track in a position relative to the surface of the first spool. Furthermore, the apparatus may include a movable track curve that allows a placement of the track curve to be moved.
