ABSTRACT:
A gravity controlled automatic paper winder for continuous type paper form a printer has a spool supported by a framework. The spool is coupled by a ratchet assembly to a motor and gear reduction assembly and permits the spool to rotate only in a direction to wind paper onto the spool. The motor and gear reduction assembly is supported only by the gear reduction output shaft and is free to rotate about the ratchet assembly. A limit switch on the framework controls power to the motor. When paper is fed from a printer to the spool, the motor and gear reduction assembly rotates downward by gravity to contact the limit switch, energizing the motor. When no paper is fed from the printer, tension due to rotation of the spool causes the motor and gear reduction assembly to rotate upward, opening the limit switch and deenergizing the motor.
