Abstract
The machine supports a roll of paper from which tubes are formed and ejected continuously. The machine includes a turret having a predetermined number of paper tube forming spindles mounted in and supported therearound. The turret is adapted and arranged to be positioned so that one paper tube forming spindle is positioned in a tube forming position with relation to a paper drive roller to form a paper tube. The turret is rotatable to move the spindle away from said tube forming position into a tube ejection position in engagement with a tube ejection means for ejection of the formed tube from the spindle.
Claims11
A machine for manufacturing paper tubes comprising
- means for rotatably mounting a roll of paper,
- paper feed rollers arranged in juxtaposition to said mounting means for the roll of paper,
- a rotatable turret,
- at least one tube forming spindle carried by said turret,
- said turret being rotatable to move said spindle to a tube forming position;
- a paper drive roller in juxtaposition to the position of said tube forming spindle when in said tube forming position,
- said paper drive roller being normally in working engagement with said spindle to engage and drive the paper between said roller and said spindle,
- a rotatable tube ejection means arranged in juxtaposition to said tube forming spindle,
- said turret being rotatable to move said spindle away from said tube forming position and out of engagement with said paper drive roller into a tube ejection position in engagement with said ejection means,
- said ejection means having a surface engagable with the outer cylindrical surface of said spindle and thus with a formed tube carried thereby and moving in a direction substantially parallel to the axis of said spindle for ejection of a formed tube from said spindle,
- said turret then being rotatable in the opposite direction to move said spindle away from said ejection means and back to engagement with said drive roller.
