Abstract
A continuous paper supply is provided from alternative supply rolls by momentarily stopping the paper being supplied and adhesively joining the leading edge of a new supply severing the old supply and accelerating the new supply. A loop of paper is paid out during the momentary stoppage of the acceleration of the new supply and is thereafter recovered in preparation for the next changeover. An idler roller senses tension in the paper and generates a signal to the supply. The idler roller is capable of skewing to equalize tension across the paper.
Claims10
Apparatus for continuously supplying paper in sequence without interruption from a plurality of supply rolls comprising:
- a. a support frame;
- b. said support frame having first and second support means for supporting first and second supply rolls of paper;
- c. first and second means for retarding the rotation of said first and second supply rolls of paper respectively;
- d. one of said supply rolls supplying paper, the other supply roll being available to begin supplying paper upon the at least partial exhaustion of the paper on said one supply roll;
- e. first means for holding the leading edge of paper from said other supply roll adjacent to paper being supplied from said one supply roll;
- f. a first roller;
- g. said paper being supplied passing over said first roller;
- h. said first roller being supported at its first and second ends by first and second arms;
- i. said first and second arms being independently pivoted whereby said first roller is free to move in rotation about a common axis and to skew;
- j. first and second pressure cylinders having plungers therein connected respectively to said first and second arms;
- k. said first and second pressure cylinders being connected to a common source of pressure;
- l. at least a second roller;
- m. said paper being supplied passing over said second roller;
- n. means for controlling translation of said second roller toward said first roller;
- o. second means for holding the paper being supplied;
- p. means for pressing the leading edge of the paper from said other supply roll against said paper being supplied;
- q. means for severing the paper being supplied while it is being held by said second means for holding whereby the supplying of paper is transferred to said other supply roll;
- and
- r. means for returning said second roller to its initial spaced position from said first roller.
