Description
ProTech radius formers are the modern way to fabricate the curb the laminate such as arched headers and radiused moldings for windows and doors.
The PT7 radius former uses a series of machine rails supporting do sets of heavy aluminum arms, which are adjusted to find a pattern to be fabricated.
The laminates are clamp to form the arms with a series of 32 specially designed pneumatic clamps
Standard compressed air, at pressures up to 200 psi, is connected to the clan via a quick disconnect
The clamp is an energized using a self-contained valve which permits the air supply to be disconnected after actuation
The PT-7 can be used as a cold press and this model is also equipped with an optional set of thermostatically controlled heat bands
Depending on the size of the component and the adhesive used the heat band can cure the assembly in as little as 20 minutes
Height: 54"
Length: 120"

Thickness: 4.5"
Straight: 42"
Diameter: 96"
Radius: 180"
Heating option: heat band
Approx. cycles per hour with heating option:
Machine wait with heat option: 3,500lbs
The air cylinders on the PT 7R rated for 200 psi air pressure
To accelerate adhesive cure time the PT-7 is equipped with a thermostatically controlled heat band system. which consist of a control system containing a programmable temperature controller coupled to a thermocouple. The controller regulates the heating temperature in cure cycle duration. The laminate are sandwiched between a set of heat fans during layup then connected to the controller upon insertion into the machine.
The standard clamp has a 6 inch stroke which provides a clamp and capacity of 4 1/2 inches
