Abstract
A web winding and cutting apparatus for mounting downstream of the final stage of a web handling machine such as a printing machine includes pressure rollers mounted upon pivoted arms and engageable with the final roller of the machine to draw the web from the final stage, so that a relatively low-torque motor can be employed to drive a core upon which a roll is round. A movable cutter blade may be associated with pivoted arms carrying joining rollers used for pressing the severed leading end portion of the web onto the core to be wound.
Claims21
Web winding and cutting apparatus for association with the final stage of a machine for the treatment of a web, such as a printing machine, comprising at least two vertical supports, rollers over which the web passes, mounted between the said supports, means for transverse cutting of the web, and a web winding unit, wherein the said apparatus includes:
- a final roller,
- a motor driving said roller;
- at least one pressure roller engageable with said final roller for drawing the web from said final stage;
- a core upon which a roll is formed by winding of the web in said winding unit,
- means for rotating said core,
- means for bringing said roll into driving engagement with the said final roller to drive the roll,
- a movable knife for engagement with the web, constituting said cutting means,
- means for joining the severed leading end portion of the web to said core,
- upper and lower pressure rollers adapted to be coupled selectively with the said final roller, and
- pressure means for urging one of said pressure rollers selectively against said final roller.
