Pullback Devices
Pullback devices use a series of cables attached to the operator's hands, wrists, and/or arms.
Pullback Device on Power Press
This type of device is primarily used on machines with stroking action. When the slide/ram is up between cycles, the operator is allowed access to the point of operation. When the slide/ram begins to cycle by starting its descent, a mechanical linkage automatically assures withdrawal of the hands from the point of operation.
The images below show a pullback device on two different power presses. When the slide/ram is in the "up" position, the operator can feed material by hand into the point of operation. When the press cycle is actuated, the operator's hands and arms are automatically withdrawn.
