Title: Improvements relating to Machines for Applying Covering Strips to Boxes of Pasteboard or similar Material.
Inventor: BLACKINTON HENRY BAKER
Filed: 1901-01-12
Granted: 1901-04-20
Abstract: 848. Blackinton, H. B., Cox, W. F., and Ginn, M. E. Jan. 12. Making paper and like boxes.-The boxes of pasteboard and like material are covered by a strip by means of apparatus such as that shown in Figs. 3 and 4. The box is placed on a holder 30 carried on an arm 29 which is mounted loosely on a shaft 3. The arm is tilted until the box abuts against the end of the covering-strip 28, which is glued on its upper surface, and presses against a press roller 9 fast on the main shaft 2, the rotation of which rotates the box-holder, and thus envelops the strip around the box. When a sufficient length of the strip has been wound on the box, a finger 16 on an oscillating shaft 15 drops into a depression in the cam 11 on the shaft 2, thus causing, under the action of a spring 17, a knife 19 mounted on the shaft 15 to move downwards to sever the strip. The main portion of the strip is at the same time moved backwards from the knife by means of a cam 12 on the shaft 2, which, through the link 24, moves backwards a movable guide 23 over which the strip passes, the strip being moved forward again, when the knife is lifted, for engagement with the next box. The pressing-roll 9 has a flange 40 which turns in the covering-strip over the mouth of the box, and in conjunction with it is a disc 10 which folds the strip over the bottom of the box. When the strip is thus partially attached, the arm 29 is turned to bring the box against a corresponding pressing-roll 36, but rotated in the opposite direction. Finally, the arm is raised into an upright position, and a plunger mounted on the shaft of the box-holder is actuated by hand to fold the strip on the inside of the mouth edge. The shaft 2 is rotated intermittently, so as to make a complete revolution between the intervals of rest, by means of a clutch having a lug which is normally arrested by an angle lever which is operated by a treadle to disengage the lug and thus permit the rotation of the shaft.
