Abstract
Abstract A wrapping machine in which paper is fed from a paper roll and wrapped around a plurality of separate intermittently fed panel boards. Means responsive to the diameter of paper remaining on the paper roll applies a gradually decreasing drag force to prevent overrunning by the paper roll. Paper passes over a capstan roll which is driven in response to the position of a vertically movable dancer roll which is cradled by and tensions the paper. The dancer roll position also engages and releases the braking device. An idler roll is provided with a downwardly inclined paper stop, the end of which is spring biased upwardly to confine paper against the idler roll and prevent backward sliding of paper when it is severed therebeneath. The paper passes through a shock-absorbing device and hence to a pair of nip rolls through which a narrower panel board having glue strips adjacent its lower edges is fed. The paper and board are then fed between lower driven belts and upper converging belts which pull the paper taut; and the paper is folded and tucked under the board edges for contact with the glue strips. Means responsive to passage of a board therethrough severs the paper between boards, and the paper end portion is pulled back through the nip.
