Abstract: A machine for folding and gluing a continuous web in high speed operation. A continuous web which has solidified glue thereon in selected regions is folded. Heat is applied to the folded web to melt the glue, particularly in specific areas of the folded web. Pressure is applied to the specific areas to urge together the folded portions of the web and the melted glue therebetween. Then the folded web travels between heat transfer members which rapidly cool the folded web and the glue between folded portions thereof. Thus, the glue is solidified and the folded portions are firmly adhesively attached together.

Abstract: Apparatus for removing curl from a continuous moving web. The apparatus includes cylindrical members for supporting and directing the continuous web during its travel and a pair of engagement members between which the web travels. The engagement members are pivotally movable so that either surface of the web can be engaged by one of the engagement members with any desired degree of pressure for removing the curl in the continuous web during travel thereof. If the curl is upwardly, the engagement members are pivoted to engage one surface of the continuous web. If the curl is downwardly, the engagement members are pivoted to engage the opposite surface of the web. The degree of pressure applied for decurl action can be adjusted by adjusting the angle of the engagement members with respect to the line of travel of the continuous web. The apparatus also includes brush members engageable with the web to control the tensional forces upon the web as the web engages one or both of the engagement members.
