In-Line Formed Core Supporting a Wound Web
A web is wound onto an in-line core instead of a separate core. At the start of the winding process, a core-forming substrate attached to the leading edge of the web is wound into an in-line core. The web is wound around the in-line core. For streaming operation, a composite substrate-web stream comprising an alternating sequence of attached core-forming substrate segments and web segments is produced. The first core-forming substrate segment is wound into a first in-line core, and the first web segment is wound around the first in-line core. The composite substrate-web stream is cut. The second core-forming substrate segment is wound into a second in-line core, and the second web segment is wound around the second in-line core. The composite substrate-web stream can be slit longitudinally to produce multiple composite substrate-web stream strips. Multiple composite substrate-web stream strips can be wound in parallel on a single mandrel.

This application claims the benefit of U.S. Provisional Application No. 61/219,428 filed Jun. 23, 2009, which is incorporated herein by reference.
CROSS-REFERENCE TO RELATED APPLICATIONThis application is related to U.S. patent application Ser. No. ______ (Attorney Docket No. 11356.0009), entitled Enveloper Assembly for Winding Webs, which is being filed concurrently herewith and which is herein incorporated by reference in its entirety.
BACKGROUND OF THE INVENTIONThe present invention relates generally to winding of webs, and more particularly to an in-line formed core that supports a wound web.
Many products are supplied as a flexible, elongated sheet referred to as a web. Examples of webs include sheet paper, sheet fabric, plastic film, and metal foil. Webs are commonly wound into a roll for storage, shipping, processing, and consumption. In typical practice, webs are wound onto a separate component, a core formed from a rigid material such as cardboard, wood, plastic, or metal. The core serves as a support structure for initiating the winding process and for maintaining the structural integrity of the web during shipping and handling. The core also serves as a mechanism for dispensing the web during further processing and during end-user applications.
Separate cores, however, suffer from several disadvantages. For example, they incur additional costs associated with their purchase, shipping, and storage; and the additional steps required to load the separate cores onto winding mandrels increase manufacturing complexity, with attendant additional manufacturing costs. Separate cores, furthermore, add to the waste stream, since the cores are typically discarded once the web has been consumed. Various coreless winding methods have been developed; however, they are typically tailored to specific materials and require complicated steps to initiate the winding. In some instances, the final roll does not maintain sufficient structural integrity as the web is consumed; consequently, the last portions of the web are wasted. What are needed are methods and apparatus that wind webs formed from a wide range of materials, reduce manufacturing costs, and reduce waste material.
BRIEF SUMMARY OF THE INVENTIONA web is wound around an in-line core. A core-forming substrate is attached to the leading edge of the web. The core-forming substrate can be attached to the web with adhesive. The core-forming substrate is wound into an in-line core, and the web is wound around the in-line core. For streaming operation, a composite substrate-web stream comprising an alternating sequence of attached core-forming substrate segments and web segments is produced. The first core-forming substrate segment is wound into a first in-line core, and the first web segment is wound around the first in-line core. The composite substrate-web stream is then cut. The second core-forming substrate segment is wound into a second in-line core, and the second web segment is wound around the second in-line core. The composite substrate-web stream can be slit longitudinally to produce multiple composite substrate-web stream strips. Multiple composite substrate-web stream strips can be wound in parallel on a single mandrel.
These and other advantages of the invention will be apparent to those of ordinary skill in the art by reference to the following detailed description and the accompanying drawings.
In embodiments of the invention, an in-line core-forming substrate is attached to the leading edge of a web. At the start of the winding process, the in-line core-forming substrate is wound into a core. The web is then wound onto the in-line formed core (for simplicity, an in-line formed core is also referred to as an in-line core). Note that the term “substrate” is sometimes used as a synonym for “web”. Herein, a “web” refers to the product of interest (such as paper towels, cloth strips, photographic film, masking tape, and metal foil). As discussed above, in general, a web refers to a flexible, elongated sheet. Web materials can be homogeneous or heterogeneous, including composites and laminates. Webs can have surface coatings, including adhesives. The body of a web can be uniform or can have geometrical features such as perforations and corrugations. The surface of a web can be smooth or textured, including features such as corrugations.
“Core-forming substrate” refers to a component used to produce an in-line formed core (as described in detail below). A wide range of materials can also be used for substrates, including paper, plastic, and metal. In some instances, the substrate material can be similar to the web material. For example, the web can be thin paper, and the substrate can be a heavier weight, stiffer paper. As another example, the web can be thin plastic film, and the substrate can be a thicker plastic film or a more rigid plastic film. Substrate materials can be homogeneous or heterogeneous, including composites and laminates. Substrates can have surface coatings, including adhesives. The body of a substrate can be uniform or can have geometrical features such as perforations and corrugations. The surface of a substrate can be smooth or textured, including features such as corrugations.

In some embodiments, a third component can be used to attach core-forming substrate 106 to the leading edge 130 of web 104. For example, in the configuration shown in
Herein, core-forming substrate 106 is attached to leading edge 130 of web 104 if core-forming substrate 106 is attached to at least one of leading edge 130, a portion of surface 210 of web 104 in the proximity of leading edge 130, and a portion of surface 212 of web 104 in the proximity of leading edge 130. Similarly, a core-forming substrate is attached to the trailing edge of the web if the core-forming substrate is attached to at least one of the trailing edge and a portion of at least one surface of the web in the proximity of the trailing edge.
Web 104 can be attached to core-forming substrate 106 by a variety of means. For example, they can be attached with an adhesive. The adhesive can be disposed on web 104, core-forming substrate 106, or both web 104 and core-forming substrate 106. The adhesive can be a thermally-activated adhesive. In another embodiment, web 104 is attached to core-forming substrate 106 with double-sided adhesive tape disposed between web 104 and core-forming substrate 106. In another embodiment, as discussed above, web 104 is attached to core-forming substrate 106 with single-sided adhesive tape. In another embodiment, web 104 is attached to core-forming substrate 106 by thermal fusion. As discussed above with reference to

Reference line 557 is the demarcation line between the trailing edge of core-forming substrate 524 and the leading edge of web 514 for the next wound web roll. Reference line 553 is the cut line that demarcates the end of wound web roll 502 and the start of the in-line core for the next web roll. If a pull tab for wound web roll 502 is desired, reference line 553 is offset from reference line 551. If no pull tab is desired, reference line 553 coincides with reference line 551.

In the embodiment shown in
The inner wrap is formed from section 1120, which has no adhesive, and the outer wraps are formed from section 1104, which has adhesive disposed on one surface. The inside surface of the finished in-line core 1140 is therefore surface 1120, which has no adhesive disposed on it. In many applications, it is desirable to have no adhesive on the inside surface. For example, exposed adhesive would attract dirt, interfere with loading the finished wound web roll onto a dispensing spindle, and interfere with handling by a user (that is, exposed adhesive would stick to fingers).

For streaming production, the sequence of core-forming substrate/web/core-forming substrate/web . . . is repeated. Herein, a composite substrate-web stream comprises an alternating sequence of attached core-forming substrate segments and web segments. Each core-forming substrate segment has a leading edge and a trailing edge, and each web segment has a leading edge and a trailing edge. To simplify geometrical descriptions herein, a core-forming substrate segment includes a core-forming substrate and any portion of web overlapping it or inserted into it.
For example, in
Under this geometrical terminology, a web segment is attached to a core-forming substrate segment. The trailing edge of a core-forming substrate segment also serves as the demarcation line for the leading edge of the attached web segment.
One skilled in the art can assemble the modules in various physical configurations. For example, all modules can be housed in a single frame. In another example, the winder module and the substrate inserter module can be housed in one frame, and the web supplier module can be housed in a second frame. In another example, the three modules can each be housed in individual frames. One skilled in the art can also group functions in various configurations. For example, the slitting operation (described below) can be grouped with the winding module or with the substrate module; the slitting operation can also be performed in an independent module.
Various components such as rollers and turrets are driven by drive systems such as electrical motors. The drive systems and the overall sequence of operations are controlled in response to commands issued by a control unit. The control unit, for example, can be a computerized control unit or a programmable logic controller control unit.
