Abstract
A system of forming a coreless roll paper product in which an elongated coreless paper roll is cut into segments by a saw. Prior to being cut from the elongated coreless paper roll, each roll segment is positioned on a support shaft located on a rotatable turret. The roll segment is severed while being supported by both an elongated mandrel and the support shaft, the blade passing through a space between the mandrel and support shaft. The turret has a number of spaced support shafts projecting therefrom, and rotation of the turret simultaneously brings the support shafts to various locations so that various steps in the operation are performed seriatim and simultaneously.
Claims16
A method of forming a coreless roll paper product, said method comprising the steps of:
- placing an elongated mandrel having an elongated coreless paper roll wrapped thereabout and a shaft into substantially axial alignment, said elongated mandrel being located in a central opening defined by said elongated coreless roll;
- while said elongated mandrel and said shaft are substantially axially aligned, moving said elongated coreless paper roll axially along said elongated mandrel toward said shaft;
- during the step of axially moving said elongated coreless paper roll, bringing said elongated coreless paper roll into engagement with said shaft;
- positioning said shaft in the central opening defined by said elongated coreless paper roll;
- terminating axial movement of said said elongated coreless paper roll after a roll segment of said elongated coreless paper roll is located on said shaft;
- severing said roll segment from the remainder of said elongated coreless paper roll while said roll segment is located on said shaft;
- and
- supporting said roll segment on said shaft.
Apparatus for forming a coreless roll paper product, said apparatus comprising, in combination:
- an elongated mandrel for supporting an elongated coreless paper roll, said elongated coreless paper roll being formed from a plurality of paper convolutions and having an innermost convolution defining a central opening receiving said elongated mandrel, said elongated mandrel having a mandrel end;
- a shaft having a shaft end;
- placement means including shaft support means for placing said elongated mandrel and said shaft into substantial axial alignment with the mandrel end and shaft end adjacent to one another;
- means for moving said elongated coreless paper roll axially along said elongated mandrel toward and on to the shaft substantially in alignment therewith whereby a roll segment of said elongated coreless roll projects beyond said mandrel end and is located on said shaft;
- and
- severing means for severing the roll segment from the remainder of said elongated coreless paper roll while said roll segment is located on said shaft whereby said roll segment will be supported by said shaft during and after the roll segment is severed from the remainder of the elongated coreless paper roll by said severing means.
