The Ultimate Non-Stick, Non-Porous Surface.
Fitted to Drying Cylinders without removal from Machine
Improve your Product and Efficiency
The build up of sticky substances on the surface of the drying cylinder is a major problem in industries such as the Paper and Textile Industries. Contamination of the surface will ultimately have a detrimental effect on the end product, either by dyes of previous products transferring themselves, marking off onto paper or a variety of other problems.
The removal of exceptionally adherent materials such as size, latex, adhesive or limescale is an operation which involves a great deal of extremely costly downtime while the build up is removed by time consuming procedures such as grinding or by these of aggressive solvents which may themselves adversely affect the surface of the cylinder.
*These problems can be eliminated by the use of Teflon® FEP sleeves.
Holscot Teflon* sleeves provide a non-stick surface which is second to none, eliminating build up and avoiding the necessity to use doctor blades. With certain particularly adherent substances a build up may occur but by virtue of the fact that FEP is inert to all chemicals and solvents, highly aggressive solvents can be used without fear of damaging the cylinder surface. The cleaning of the cylinder can be done in a fraction of the time and the end result is less downtime, more efficient use of production time and - even more important - a better product.
The sleeves are usually 0.5mm thick and manufactured in FEP, a melt processable equivalent of PTFE which exhibits all the same non-stick and chemically resistant characteristics. The sleeves are butt-welded using highly sophisticated equipment and techniques developed by Holscot to produce a seam which is virtually imperceptible. The sleeves are then transformed into heat shrinkable sleeves and the internal surfaces are chemically etched to provide a surface to which adhesive can grip.
In many cases, the cylinders cannot be removed from the machine. Holscot uses welding technology developed and refined by them to carry out the installation of the sleeves whilst the cylinder is still in place in the machine.
Worldwide Fitting
The use of Teflon* sleeves on Drying Cylinders has been widely recognised throughout the world and our teams of engineers have travelled extensively throughout Europe, Scandinavia and as far away as India to carry out on site fittings with the help of a network of agents and distributors.
In addition to Holscot's units in the Netherlands and Germany, Holscot has agents or distributors in the following territories:
France, Belgium, Spain, Italy, Sweden, Finland, Thailand, Singapore, Malaysia, China, Taiwan, India, Indonesia.
Large Diameter Rollers
The same benefits afforded by a TeflonŽ sleeve can be offered to rollers of any diameter. Our range of Seamless sleeves for rollers 1" to 15" (25mm to 410mm). Welded sleeves can be fitted to all other sizes of rollers from 15" (310mm) upwards. These are fitted to any substrate of roller- rubber, steel,aluminium, chrome, glass fibre- either at your works (generally out of the machine) or at our factory in Grantham.
