Abstract
Sticks of gum are fed individually to the bottom of a stack where each stick is raised by an elevator wheel to form the stack between side guides pivotally mounted, and biased toward one another. Each side guide has an abutment to keep the stack aligned vertically, and a presser foot resiliently holds the stack from above so that a pusher can move the stack out of the stacking station, into a wrapper, and thence into a tumble box for further handling.
Claims7
In an apparatus for receiving sticks of product fed individually to a stacking station and for moving the stack of sticks in a downstream direction out of the stacking station for further handling, the improvement comprising
- a. means for elevating each stick fed to the stacking station to allow the next stick to be fed into the bottom of a stack of sticks,
- b. side guides at the stacking station for guiding the sticks so elevated,
- c. mounting means for supporting said side guides for limited movement toward and away from the sides of the stack, and
- d. biasing means for urging the side guides inwardly toward one another to keep the stack oriented in centered vertical relationship therebetween,
- e. said side guides including abutments on their respective downstream edges for supporting and guiding the stack as succeeding sticks are fed into the bottom of the stack at the stacking station.

- b. side guides at the stacking station on for guiding the sticks so elevated,
- c. mounting means for supporting said side guides for limited movement toward and away from the sides of the stack, and
- d. biasing means for urging the side guides inwardly toward one another to keep the stack oriented in centered vertical relationship therebetween,
- e. said side guides pivotally mounted on shafts disposed below and parallel to the path of downstream movement of the stack.
