Abstract
A rewinder for winding a web to produce a rolled product. The rewinder includes a web transfer device that is used for conveying the web. The web transfer device communicates with a core in order to wind the web via surface winding. At least one pair of rotationally driven end chucks are located proximate to the web transfer device. The end chucks engage the core and the web is wound onto the core via center winding by the rotating end chucks. Also, the web is wound onto the core to form a rolled product by a combination of the center winding and the surface winding.
Claims29
A rewinder for winding a web to produce a rolled product comprising:
- a web transfer device for conveying a web, the web transfer device communicating with a core in order to wind the web onto the core via surface winding;
- at least one pair of rotationally driven end chucks located proximate to the web transfer device, the end chucks engaging the core whereby the web is wound onto the core via center winding by the rotating end chucks;
- and
- wherein the web is wound onto the core to form a rolled product by a combination of the center winding and the surface winding.
A rewinder for winding a web to produce a rolled product having a core, comprising:
- a web transfer device for conveying a web, the web transfer device communicating with a core in order to wind the web onto the core to form a rolled product having the core;
- an air blast device located proximate to the web transfer device for aiding transfer of the web from the web transfer device to the core;
- an applicator located upstream from the air blast for applying adhesive to the web;
- and
- a tension roll located upstream from the applicator, the tension roll engages the web and applies tension to the web;
- wherein the web is wound onto the core by a combination of center winding and surface winding.
A rewinder for winding a web to produce a rolled product comprising:
- a web transfer device for conveying a web;
- an odd set of a plurality of rotationally driven end chucks located proximate to the web transfer device for engaging a core onto which the web is wound;
- an even set of a plurality of rotationally driven end chucks located proximate to the web transfer device for engaging a core onto which the web is wound;
- and
- wherein the positioning and rotation of the odd set of end chucks is controlled independently from the positioning and rotation of the even set of end chucks.
A rewinder for winding a web to produce a rolled product comprising:
- a web transfer device for conveying a web;
- an odd set of a plurality of rotationally driven end chucks located proximate to the web transfer device for engaging a core onto which the web is wound;
- an even set of a plurality of rotationally driven end chucks located proximate to the web transfer device for engaging a core onto which the web is wound;
- wherein the positioning and rotation of the odd set of end chucks is controlled independently from the positioning and rotation of the even set of end chucks;
- and
- wherein the web is wound onto the core to form a rolled product by a combination of center winding from the end chucks and surface winding by the core and web transfer device.
A rewinder for winding a web to produce a rolled product comprising:
- a web transfer device for conveying a web;
- an odd set of a plurality of rotationally driven end chucks located proximate to the web transfer device for engaging a core onto which the web is wound;
- an even set of a plurality of rotationally driven end chucks located proximate to the web transfer device for engaging a core onto which the web is wound;
- wherein the positioning and rotation of the odd set of end chucks is controlled independently from the positioning and rotation of the even set of end chucks;
- a winding belt disposed to wind the web onto the core via surface winding, the core is located between the winding belt and the web transfer device while the web is wound onto the core to form a rolled product.
A rewinder for winding a web to produce a rolled product comprising:
- a web transfer device for conveying a web;
- an odd set of a plurality of rotationally driven end chucks located proximate to the web transfer device for engaging a core onto which the web is wound;
- an even set of a plurality of rotationally driven end chucks located proximate to the web transfer device for engaging a core onto which the web is wound;
- wherein the positioning and rotation of the odd set of end chucks is controlled independently from the positioning and rotation of the even set of end chucks;
- and
- a cam communicating with the end chucks to move the end chucks and the core, the end chucks are urged against the cam in a vertical direction to compensate for changes in the diameter of the web wound onto the core.
A rewinder for winding a web to produce a rolled product having a core comprising:
- a web transfer device for conveying a web;
- a core located proximate to the web transfer device onto which the web is wound onto the core to form a rolled product having the core;
- and
- an applicator located proximate to the web transfer device for applying adhesive to the web;
- wherein the web is would onto the core by a combination of center winding and surface winding.
A rewinder for winding a web to produce a rolled product having a core comprising:
- a web transfer device for conveying a web;
- a core located proximate to the web transfer device onto which the web is wound onto the core to form a rolled product having the core;
- and
- an applicator located proximate to the web transfer device for applying adhesive to the leading edge of the web to assist in transfer of the web from the web transfer device onto the core, the applicator applies adhesive to the trailing edge of the web to fix the trailing edge of the web onto the web that is wound onto the core;
- wherein the web is wound onto the core by a combination of center winding and surface winding.
