Abstract
Cylindrical rolls of paper (1, 96, 315) are completely enclosed with wrapping material (105) by simultaneously rotating the roll about its longitudinal axis and rotating the roll end-for-end. A turntable (35, 200) may be used to rotate the roll end-for-end, and a drive roll (65, 265) carried by the turntable is driven to rotate the roll about its longitudinal axis during rotation of the turntable.
Claims2
Apparatus for completely covering a cylindrical object having a longitudinal axis, a curved peripheral surface and spaced end surfaces with a web of wrapping material comprising, in combination:
- turntable means adapted for rotation in a generally horizontal plane;
- rotatable drive roll means on the turntable means and adapted to drivingly engage the curved peripheral surface of the cylindrical object;
- idler roll means on the turntable and spaced from the drive roll means to form a cradle therebetween within which a cylindrical object to be wrapped is carried;
- means pivotally supporting the idler roll for movement between a lowered first position and a raised second position;
- means for supplying a web of wrapping material to an end surface of the cylindrical object;
- means for simultaneously rotating the turntable means and the drive roll means to rotate the cylindrical object in a horizontal plane while simultaneously rotating it about its longitudinal axis and thereby cover the curved peripheral surface and the end surfaces of the cylindrical object with a series of spirally-wound overlapping rows of wrapping material;
- means to pivot the idler roll to its raised second position to eject a wrapped cylindrical object from the apparatus
- the means for simultaneously rotating the turntable and the drive roll means including a reversible motor arranged to rotate the turntable means and the drive roll means when rotating in a first direction and arranged to drive the means to pivot said idler roll to its raised second position when rotating in a second direction opposite to the first direction.
