Abstract
338,997. Holmes & Co., Ltd., J. H., Miller, R. B., and Robertson, A. T. Sept. 4, 1929. Feeding webs.- In a web-renewing mechanism f o r printing or other machines, the rotation of the new roll about its own axis before it is brought into contact with the old web is effected automatically by the movement of the roll-carrying frame or a part of its driving mechanism during the translation of the new roll to the joining position. In one form, Fig. 1, the rotation of the roll-carrying frame B closes a clutch to cause the rotation of driving discs J<1> engaging the surface of the new roll A<1>. The discs J<1> are carried by a frame H pivoted on a shaft E driven by gearing from the printing &c. machine and are driven from a chain-wheel F normally loose upon the shaft E but adapted to be clutched thereto, by the partial turning of a shaft K when a cam L on the gear wheel B' driving the frame B engages with a roller M<3> on an arm M' on the shaft K. The arm M' is loose upon the shaft K and is of right-angled form, one arm carrying the roller M<3> and the other engaging between a pair of screws M<5> carried by lugs on a hand lever M<4> fixed to the shaft K. The screws M<5> permit of a slight adjustment of the arm M<1> relatively to the shaft K and the handlever permits operation of the clutch independently of the cam L if desired. Instead of a mechanical clutch an electromagnetic clutch controlled by the roll-carrying frame may be employed. In another form, the discs J<1> are driven by chain gearing from a shaft carrying a pinion gearing with the wheel B<1>, and in a third form, the axle of the new roll is provided with a pinion adapted to engage a stationary but preferably spring-supported rack during its movement of translation to the joining position.
