New range of ball bearing pressure rollers for roof layers

Sievert are launching a new range of pressure rollers for professional roof layers. The new ball bearing pressure rollers are fitted with ergonomical wooden handles. The rollers come in several different models for work with both hot and cold seaming of varying layered seams in, for example, membrane roofing.
The new pressure rollers are used to seam membrane roofing using hand welding, for example with Sievert’s hot air tools. Although these can also be used for membrane that is cold seamed with different types of glue.

‘Correctly welded membrane is essential to the overall weather proofing of the roof ‘ said Mikael Brelin, President and CEO at Sievert AB. ‘ The right sort of pressure roller is essential to attaining optimum results with hand welding. And each of the various membranes and welding methods require their own particular roller.’

Eleven family members
Consequently Sievert rollers, manufactured in Germany, come in several sizes and in such materials as silicon, steel and PTFE-plastic. There are a total of eleven models in the new range, including seam testers.
The wooden handles are ergonomically designed to allow the roof layer to apply the required pressure easily when scarfing. The integral ball bearings allow the roller to run lightly over the work surface and the working life of the pressure roller is thus maximised.

The large range of pressure rollers in this new family allows us to always be able to offer a range of the highest quality to meet the requirements of roofers,’ said Mikael Brelin.
The silicon pressure rollers come in three widths; 28, 45 and 90 millimetres. In addition there is a medium sized roller with a 45° angled handle. The heavy steel pressure rollers come in sizes 40 and 60 millimetres. The PTFE- plastic press rollers are for joint welding of TPO, FPO and similar materials. Press roller diameter is 33 millimetres.
The range includes two press rollers in metal and two in brass for work on corners and edges. These rollers are also used for flooring work.
