PURPOSE:To improve the fixation of a transfer rib to a transfer stencil and to facilitate the release from a transfer roller by forming the forming groove part of the transfer roller with a material incohesive to the resin. CONSTITUTION:In the production of a spacer plate for corrugated fiber board, a layer built cell, etc., having an interval retaining structure, the part of the forming groove 1 in the transfer roller 2 is formed with an incohesive resin such as tetrafluoroethylene or an incohesive and elastic material such as silicone rubber. When the molten strongly adhesive resin of hot-melt type is supplied into the annular forming groove 1 of the transfer roller 2 from a nozzle 3, the resin is filled into the forming groove 1 and constrained by the dimensions and shape of the groove. Subsequently, a resin rib is continuously formed on one face of a stencil by the transfer insusceptible to disturbances. Accordingly, the fixation of the resin rib to the stencil is improved, and the release from the transfer roller is facilitated. |
