Abstract
The invention relates to a winding machine which winds a very thin metallic sheet at a high speed automatically with a winding drum pressed against a drive roll and driven by the frictional torque of the latter and air blown in a direction same with that of travel of the sheet.
Claims3
A winding machine comprising a rotatable winding drum which is movable in a direction parallel to a direction of movement of a very thin metallic sheet, a drive roll for rotating the winding drum by a frictional force, characterized by first and second hollow frames each having guide plates for the sheet in the form of a concave comb facing said sheet and disposed transversely with respect to the direction of movement of said sheet, said plates being disposed so that their longitudinal direction is in parallel to the direction of movement of the sheet, and air nozzles for blowing of air into the hollow frames in the same direction as the direction of movement of the sheet, whereby the speed of air flow at each side of the sheet is greater than the air flow at the central portion thereof.
