Abstract
Continuously running web material is transferred from a dryer, or the like, to a proximate calender, or the like, along flutter suppressing foils. The web may be calendered in a nip between a rotary calender roll and a reel drum with which a reel core is in nip relation for winding the web on the core. The calender may comprise a single roll or a plurality of rolls. A split torque arrangement is provided for the reel drum and the reel core. Especially useful for handling creped tissue paper web.
Claims35
Apparatus for handling a continuously running creped tissue web following creping at a creping roll, comprising:
- a calender located proximate said creping roll to receive the web after a short draw span between the creping roll and the calender;
- flutter suppressing means along which the web is adapted to travel in said draw span substantially flutter-free at high speed;
- said calender including a rotary calender roll;
- a rotary reel drum adapted for calendering nip cooperation with said calender roll;
- and web winding means including a rotary reel core adapted to be rotatably driven by nipping with said reel drum for winding the web onto the reel core.
Apparatus for handling a continuously running creped tissue web following creping at a creping roll, comprising:
- a calender located proximate said creping roll to receive the web after a short open draw span between the creping roll and the calender;
- said calender including a rotary calender roll;
- a combination rotary calender and reel drum adapted for calendering nip cooperation with said calender roll;
- and web winding means including a rotary reel core adapted to be rotatably driven by nipping with said reel drum for winding the web onto the reel core.
Apparatus for handling a continuously running creped tissue web following creping at a creping roll, comprising:
- a calender roll located proximate said creping roll to receive the web after a short free draw between the creping roll and the calender;
- a rotary reel drum onto which the web is trained to run from said calender roll;
- web winding means including a rotary reel core adapted to be rotatably driven by nipping with said reel drum for winding the web onto the reel core;
- and means for rotatably driving said drum and reel core in split torque relation wherein the torque in said reel core is progressively increased substantially proportionate to increase in the diameter of the roll of web as it winds onto the reel core, whereby to maintain substantially uniform bulk in the wound web.
A method of handling a continuously running creped tissue web following creping at a creping roll, comprising:
- transferring the creped web at high speed a short draw span from the creping roll to a proximate calender including a rotary roll;
- suppressing flutter of the web as it travels said draw span at said high speed;
- calendering the web in a nip of said calender roll with a rotary reel drum;
- and rotatably driving a reel core by nipping the reel core with said reel drum and thereby winding the web onto the reel core.
A method of handling a continuously running creped tissue web following creping at a creping roll, comprising:
- transferring the creped web at high speed across a short draw from the creping roll to a proximate calender including a rotary roll;
- calendering the web in a nip of said calender roll with a rotary reel drum;
- and rotatably driving a reel core by nipping the reel core with said reel drum and therby winding the web onto the reel core.
A method of handling a continuously running creped tissue web following creping at a creping roll, comprising:
- transferring the creped web at high speed across a short draw from the creping roll to a calender roll;
- running the web from said calender roll onto a rotary reel drum;
- rotatably driving a reel core by nipping the reel core with said reel drum and thereby winding the web onto the reel core;
- and splitting the torque relation between the reel drum and the reel core and progressively increasing the torque in said reel core substantially proportionate to increase in the diameter of the roll of web as it winds onto the reel core, whereby to maintain substantially uniform bulk in the wound web.
