Apparatus for rolling a sheet comprises (a) structure to receive the advancing sheet and to roll same, (b) that structure including supports over which the sheet travels, and auxiliary mechanism including first and second swingable arms and hold-down and dump rollers carried by the respective first and second arms to be movable between primary positions in which the hold-down and dump rollers are relatively collapsed toward one another for initiating sheet coiling, and a series of extending positions, in which roll-up of the sheet is guided toward completion into a built-up roll and the hold-down and dump rollers are increasingly spaced apart. |
