摘要:
A snake feeding device comprises a base having opposite ends, an actuator pivotally mounted on the base, and first and second sets of drive rolls spaced apart in the direction between ends of the base. Each set includes a roll on the base and two rolls on the actuator for engaging a snake therebetween and displacing the snake relative to the base in the direction between the ends thereof in response to rotation of the snake. The actuator selectively displaces the rolls of each set relative to one another.
