Claims7
A method of forming a coreless roll paper product, said method comprising the steps of:
- winding a paper web about and directly onto an elongated mandrel having an end during rotation of said mandrel;
- terminating rotation of said elongated mandrel after an elongated coreless paper roll having a predetermined outer diameter is formed by the wound convolutions of said paper web;
- severing said elongated coreless paper roll from said web;
- extracting said elongated coreless paper roll from said mandrel by relatively moving said elongated coreless paper roll and said mandrel;
- during said extracting step, passing the mandrel end through said elongated coreless paper roll;
- and
- while passing the mandrel end through said elongated coreless paper roll, cutting said elongated coreless paper roll seriatim into coreless roll product segments at preselected locations on the elongated coreless paper roll after said coreless roll product segments are no longer disposed about said mandrel and said preselected locations are spaced and removed from said mandrel end.
