PTA 500

Model PTA 500 applies the protective tape (nitto tape) on the profiles passing one after the other in line. When a certain aluminium bar is covered in its full length, its feeding stops automatically and is continuing only after the next Aluminium bar is presented by the operator to the driving rolls.

There is a foot switch which enables the operator to stop the profiles' movement for a moment in order to cut the protection tape between the 2 profiles and separate them by pushing the finished one at the side. At this push at side operation he is helped by a worker placed at the other end of the free roller table receiving the usually 6 meter aluminum profile bar.

The machine is suitable for applying adhesive tape on up to 6 faces and inclined sides simultaneously and also curved surfaces of aluminium profiles. Protection adhesive film is applied simultaneously on the upper, lower and if so needed the side faces and inclined sides too of the Aluminium sections.

Machine composed by a screw-bolt mounted Body on base made out of ITEM anodized structural aluminium system for mechanical constructions, supporting 2 main driving rolls, vulcanized high endurance special rubber cast and rectified, plus the 2 tape application mechanisms for vertical side application and the 2 extra inclined sides tape application units for applying the protection tape at various acute and blunt angles.

There are always soft position adjustable rolls for ironing the tape but also for achieving the tape application on curved surfaces. The driving roll station is in bridge form construction. The upper free rubber roller is held by carriers vertically sliding on double linear ITEM bearings.
