APPARATUS FOR APPLYING PRESSURE SENSITIVE ADHESIVE TO GLASS FIBER MESH MATERIAL

摘要

Adhesive coating equipment having an adhesive reservoir heated by circulating electrically heated oil. A first lower hollow roller is mounted above the reservoir having a lower portion immersed in the adhesive contained in the reservoir. A power driven second hollow top roller is mounted above and in contact with the first roller and rotates the first roller transferring adhesive from the reservoir to the first roller and then to the top roller for coating a web passing over the top of the second roller. The rollers are heated by heated oil circulated through the interior of the rollers to maintain the rollers and adhesive at the same temperature and the adhesive at the same viscosity throughout the transfer of adhesive from the reservoir to the web. An idler roller is located adjacent to the lower and top rollers for maintaining at least a predetermined minimum arcuate length of web contact with the second or top roller.
