Title: Improved mechanical means employed in the drying of printed wall papers
IPC: D21F5/00
Filed: 1920-04-26
Abstract: 168,110. Shorrock, J., and Wall Paper Manufacturers, Ltd. April 26, 1920. Drying materials in long lengths.-Relates to apparatus of the type in which printed wall paper and other material is passed through the drying- chamber in festoon form upon horizontal rods attached to a travelling chain and consists in pivoting the rods to brackets which are hinged to the chain, means being provided for delivering the dried material from the rod and opening and rapidly closing the hinges so that the rods take up the material from the feeding device. As shown, the rods g<1>, Figs. 2 and 3, are pivoted to shoes g attached to hinges e which are secured to the chain a. During their passage through the chamber, the rods are supported upon the edges of the chains b in an horizontal position, the speeds of the chains a, b being the same. After traversing the chamber and the chains b, the rods fall to a vertical position and deliver the dried material to other rods beneath them. The rods g<1> then traverse an incline i<1> formed on the frame i of the apparatus and are returned to an horizontal position, the hinges being opened by the drag on the rods as shown in Fig. 3. As the shoes pass around the sprocket c, they are struck by a bar o, Figs. 7 and 9, so as to close the hinges and thus cause the rods to swing rapidly and pick up the material from the supporting-rod m of the feeding-device. The bar o is actuated through pivoted bars n, n<4>, n<3>, by means of a knife-edge m<1> formed upon the rod m, which is attached to the travelling chain l of the feeding-device and which engages with the lower end of one of the bars m. The striking of the shoes by the bar o and the forming of the festoons is facilitated by the feeding chain l travelling at a greater speed than the chain a.
