Pneumatic extractor for extracting soles from the mould which present particular resistance due to the design and/or back taper.
Screw model, suitable for extracting soles with high heel and with wooden insert positioned in the heel part of the sole itself.
The sole is extracted in 3 stages:
1 –the pneumatic switch is used to screw the tool/screw in the sole. This switch remains pressed until extraction is complete.
2 – the second pneumatic switch is used to control two cylinders which press against the mould in order to extract the sole.
3 – when the pneumatic switch is released, the tool/screw rotates in the opposite direction and frees the sole.
