ABSTRACT:
A power driven dual shaft, parallel axis take-up apparatus is disclosed having an alternately driven take-up spool mounted on each of the shafts. An outer protective door is provided for each of the spools, each door being pivotally supported for movement between a closed position to provide frontal protection, and an open position to permit access to the respective spool. An inner protective door is pivotally mounted between each outer door and its respective spool for pivotal movement from a first frontal protective position between each spool and the respective outer door and a second protective "slap-guard" position between the spools whereby outer door and inner door protection is provided. The doors are sequentially operative to provide selective access to the spools and protective shielding therebetween. In particular, the inner doors provide simultaneous multi-function action to conveniently cut the elongated flexible stock while simultaneously providing screen door protection between the spools as well as guiding the stock so as to be conveniently snagged for winding onto the empty spool. The respective pairs of doors interlock with each other such that when each outer door is in the open position rotation of the respective inner door to the frontal protective position is prevented by interference with the respective outer door. When each outer door is in the closed position during winding of the respective spool, the inner door prevents opening thereof.
