Thermal edge folding is a process for connection of textiles with plastics. It is often used in the automotive industry in the field of pillar panelling (e.g. A-column; B-column; C-column, etc.). This process does not create an adhesively joined connection, but the basic textile fibres grip into the melted plastic material.
a solid basic frame with a metal sheet/makrolon panelling
a servomotor spreader for the main stroke
a control cabinet with transformer to be connected ahead, if needed
a clearly arranged operating panel
a service door for simple repair and maintenance
The machine is manufactured in lean design. This makes possible operation in continuous production, which means the parts can be processed from manufacturing to refining to packaging.
a solid basic frame (standard basic concept)
the lower tool on which the welding nest and all slides and part detections are mounted
the upper tool which contains the hot plate element segment and the pneumatic actuators for the welding stroke
optionally a handling for the empty welding nest
The parts are loaded into the tool’s welding nest
Trigger off START
The slides fold the textile overlap (STEP 1 & 2 in pic. 5 and 6)
The servo-motor spreader moves the prestroke into operating position (shortly above the part)
The pneumatic actuator units in the upper tool come out and connect the textile with the carrier material
The servomotor spreader moves to the unloading position, simultaneously grippers in the upper tool unload the part from the welding nest (option)
Load the next part and unload the welded parts
The process starts anew.
