Problems solved by technology

Therefore, it is economically advantageous to use thicker rather than thinner paper stock, but as the thickness of the paper stock increases it becomes increasingly difficult to adhere the trailing edge evenly to the underlying layer of paper stock

Abstract

The convoluted tube (1) is formed from a composite sheet comprising a first sheet (6) and a second sheet (5). The convoluted tube comprises a first section (66) formed by a plurality of convoluted layers (2) of the first sheet, a first section (66) formed by the directly bonded and overlapping portions of the first sheet and the second sheet Two sections (70), and a third section (68) formed by a second sheet wrapped around and overlying the first sheet. The second segment is the portion of the lower cladding located between the layers of the first sheet and the layers of the second sheet.

Description

technical field [0001] The present invention relates to a convoluted tube formed from a plurality of convolutedly wound, adhesively secured sheet material and a method for manufacturing the convoluted tube. Background technique [0002] The conventional construction of convoluted tubes (sometimes called parallel tubes) and the conventional method of manufacturing such tubes using winders are known eg from US3073218, US3190195, US3585908 and US3869325. Conventional winders generally include mechanisms for the following purposes: initially feeding a continuous sheet of paper or board from a paperboard roll or reel, preparing the edges of the paper by scraping, coating the surface of the paper and the scraped edge with glue, The paper is cut to a predetermined length that corresponds to the length of the reel tube to be prepared (the paper width is determined by the width of the reel), with the leading edge of the paper advanced into the slotted mandrel onto which it will be wo...
