A feed device and a strand pelletizer including the feed device and a cutting mechanism having a rotationally drivable cutting rotor and a counter-knife cooperating therewith. The feed device has a pair of feed rollers rotatable in opposite directions in order to feed strands to the cutting mechanism. At least one of the feed rollers is mounted transversely to a longitudinal axis of the mounted feed roller in a movable manner by a movable roller suspension. An adjustment actuator linked to the movable roller suspension can be used to adjust a gap between, and/or the contact force between, the feed rollers. The adjustment actuator has an articulation point on the movable roller suspension and an articulation point on a cutting mechanism support on which the cutting rotor is mounted, so that the movable roller suspension and the cutting mechanism support are directly connected by the adjustment actuator.

Provided are a paper holding mechanism and a paper shredder. In the paper holding mechanism, a placement chamber is disposed in the housing. The placement chamber includes a conveyor section and a placement section that communicate with each other. An included angle is set between the conveyor section and the placement section. The housing is provided with a first paper inlet at the conveyor section. The first paper inlet communicates with the conveyor section. The paper feed assembly is disposed on the housing. The first paper press member is disposed on the housing. The width of the placement section at the first paper press member is variable.

A paper shredder capable of feeding paper laterally, a paper holder, a curved paper box, a paper pick-up assembly, and a paper shredding assembly. The paper holder connects with the curved paper box. A paper holding plate is disposed on an upper surface the paper holder close to the curved paper box, and the first paper holding plate and/or the second paper holding plate incline downwards toward the paper inlet. The paper pick-up assembly is disposed in the first paper holding plate and is close to the paper inlet. The paper shredding assembly is disposed below the paper inlet, and the end, away from the curved paper box, of the paper is driven by a paper pick-up assembly to enter the paper shredding assembly through the paper inlet.
