PROTECTIVE SLIDE FOR A WORK MACHINE

A protective slide assembly for a work machine for processing packaging material includes an assembly element for connecting the protective slide assembly to the work machine , a protective element arranged to be movable relative to the assembly element, a first sensor element , and a second sensor element fixedly arranged at the assembly element . The protective element can be moved relative to the assembly element between a release position and a protection position, and the first sensor element and the second sensor element are configured to come into contact in the protection position of the protective element and to output a signal that is indicative of the contact. The first sensor element is arranged such that it can be moved along with the protective element and an amplitude of motion of the first sensor element is greater than an amplitude of motion of the protective element.
