A shredding machine is disclosed for shredding sheet material such as paper documents. The machine comprises an electric cutting mechanism which is operable to shred the sheet material, and has a collection bin arranged below the cutting mechanism for collection of the resulting shreds. The collection bin is movable in a pivotal manner between a first position in which it permits operation of the cutting mechanism and collects the shreds, and a second position in which it stops operation of the cutting mechanism. The bin is configured to move from the first position to the second position in response to the weight of shreds collected in the bin and the force acting on the collected shreds by fresh shreds exiting the cutting mechanism exceeding a predetermined threshold value.
A shredding machine for shredding sheet material, the machine comprising an electric cutting mechanism operable to shred sheet material fed in to the machine, and a collection bin arranged for movement between a first position in which it permits operation of the cutting mechanism and collects shreds from the cutting mechanism, and a second position effective to stop operation of the cutting mechanism, wherein the bin is configured to move from the first position to the second position in response to a force acting on the shreds collected in the bin exceeding a predetermined threshold value, and wherein movement of the collection bin from the first position to the second position is effective to stop the cutting mechanism only after the passage of a predetermined period of time.
