Hot melt roll coaters are used for the application of hot melt adhesive to leather, plastics, paperboard, foam, and many other materials. This hot melt gluing machine can apply almost any type of hot melt adhesive – including pressure sensitive hot melts and hot melt adhesives with long open time.
The hot melt roll coater applies a thin layer of hot melt adhesive to the part as it passes over the coating roll. Coating thickness can be adjusted with a dial on the top of the machine. The coating roll applies a thin layer of hot melt to the part, but the layer cools quickly, and the part can be handled immediately as it exits the gluing machine. A powered feed roller presses the part against the coating roller to be sure that it receives a full coating of glue. This machine has two electronic temperature controls. One is for the adhesive melt chamber, and the other for the coating roller tank. The dual controls allow precise control of adhesive temperature – within 1 degree F.
|Hot Melt Roll Coaters – RT Series
RT hot melt roll coaters are adhesive application machines used to apply hot melt adhesive to sheets of material up to 39.5 inches wide. These hot melt roll coaters have a large adhesive reservoir and a powered feed roller system for coating thin parts and wide sheets and are available in 3 working widths: 13”, 26” & 40”. The feed roll can be released and pivoted out of the way to make the RT an open roller coating machine for hand-held parts.
The feed roll system on the Schaefer RT is adjustable to allow coating of parts as thin as .020, and as thick as 6″. The machine is equipped with variable speed drive, and also has a simple adjustment for coating thickness. Adhesive temperature is controlled by an electronic temperature control and solid state circuitry. Hot melt adhesive can be added by simply raising the feed table and loading fresh adhesive to the melt chamber. There is no need to stop operation while waiting for adhesive to melt. The RT can operate with almost any type of hot melt adhesive having an application temperature below 400 F. It is mounted in a roll around base, so it can easily be relocated to a new work area.
Hot Melt Coaters – HM Series
The Schaefer HM series hot melt roll coater has a cantilevered feed roller, so it can be used to apply adhesive coating to either a strip along one edge of a part or it can be used for adhesive application to the full surface of the part (up to the full width of the coating roller). An adjustable feed guide is mounted to the feed table to ensure consistent and accurate adhesive application when coating only a section of the part. The MH series is available in 3 working widths: 3”, 9” and 14”.
This machine is used for glue application in many different applications: shoe manufacturing, leather goods assembly, foam fabrication, packaging, product labeling, automotive interior parts and many other types of product gluing and assembly work.
HRC Hot Melt Gluing Machine
The HRC hot melt gluing machine is a table top hot melt roll coating machine designed for gluing foam blocks and small parts with hot melt adhesive. It has an adjustable height driven pressure roll for thin parts. The roll can be pivoted back to make the coater an open roller machine for the gluing of hand held foam blocks or the sides of larger parts.
The HRC also has a unique secondary glue pickup roll below the coating roll that allows the use of a deep glue tank – resulting in higher capacity and more running time before adhesive needs to be added. This machine is ideal for coating parts made of foam, chipboard, corrugated, leather, and many other materials.
