Abstract: The present invention relates to a shredder with an automated lubricating system.

Abstract: A lubricating pack specifically designed for paper shredders, including a piece of oiled paper saturated with lubricant placed between two jackets that are each provided at an inner layer thereof with an oil-seepage-proof film.

Abstract: A shredder holds a cutting blade assembly including a motor and a gear box inside its case and has a trash bin for collecting paper chips underneath the cutting blade assembly. A swinging board is provided in the vicinity of the paper outlet of the case. The swinging board is connected to a transmission axis via a shaft.
