Embodiment Construction

[0024] The present invention relates to an apparatus for forming coreless paper rolls. The apparatus includes an expansible mandrel that can be used in conjunction with an existing rewinder. The mandrel is segmented, with the segments expanding when the mandrel is loaded into the rewinder. While in the rewinder, a web of material, such as the type used to form register receipt rolls, is wound upon the mandrel. After a sufficient amount of material has been taken up, the mandrel can be removed. Upon removal, the segments of the mandrel contract, whereby the cross section of the mandrel is reduced and the roll can be removed. The result is a coreless roll of material.

Rewinder Apparatus

[0025]FIG. 1 illustrates a rewinder 10 that can be used in conjunction with the mandrel of the present invention. More specifically, the depicted rewinder is a surface winder sold by Dusenbery Worldwide. As is known in the art, such rewinders include a supply roll 20 from which a web of material 22 is...

Abstract

Disclosed is an apparatus for forming coreless paper rolls. The apparatus includes an expansible mandrel that can be used in conjunction with an existing rewinder. The mandrel is segmented, with the segments expanding when the mandrel is loaded into the rewinder. While in the rewinder, a web of material, such as the type used to form register receipt rolls, is wound upon the mandrel. After a sufficient amount of material has been taken up, the mandrel is removed from the rewinder. Upon removal, the segments contract whereby the cross section of the mandrel is reduced and the roll can be removed. The result is a coreless roll of material.

Description

RELATED APPLICATION DATA [0001] This application is a continuation-in-part of co-pending application Ser. No. 60 / 629,327 filed on Nov. 17, 2004 and entitled Coreless Winding Apparatus, the contents of this application are fully incorporated herein.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to a coreless winding apparatus. More specifically, the present invention relates to a rewinding apparatus that employs an expansible mandrel whereby coreless rolls of paper can be created. [0004] 2. Description of the Background Art [0005] Devices for use in constructing coreless rolls are known in the art. For instance, U.S. Pat. No. 4,695,005 to Gietman discloses a winder for making coreless rolls of pliable sheet material, such as plastic, cloth, or paper. The paper is initially rolled about a pair of rods and after a sufficient amount of material has been wound, the rods are collapsed towards one another. Thereafter, an air cylinder is activated...
