Automatic hot air welding machine for PVC covers
SM-321-HA
SMRE Engineering
S.M.R.E. developed SM-321-HA - a new hot air welding solution for the automatic production of covers in PVC with hot air welded reinforcing strips or omega profiles.
SM-321-HA is a high performance unwinding, welding and square cutting system that automatically carries out the following functions:
* Unwinding of the PVC sheet - loaded onto a transportation trolley - off of the roll
* Square cutting with pentagonal electric blade
* While the sheet is pulled through the machine 5 or more hot air welding heads - the distance of which is manually regulated on the machine bridge - hot air weld a reinforcing strip, an anti-vandalism strip or an omega profile to the fabric. The operator can choose the number of hot air welding heads that are to be employed. The maximum number of installable welding heads is 7.
* At set intervals, another hot air welding head welds a transversal reinforcing strip.
* Once the sheet is at the desired length, an electric cutting blade square cuts the fabric off of the roll.
* On the other side of the cutting bridge the fabric is deposited into a trough.
