Abstract:
Coreless spools, alternately wound on two spindle mounted mandrels from a continuous web supply of thin sheet material, are jet propulsively ejected from the mandrels by pressurized fluid conducted thereto. Loose end portions of the completed spools are rewrapped about the spool body by bridging a gap between two conveyors and two air curtains.
Abstract:
Each one of a pair of pivot arms is pivoted at one end to a stationary support, the pivots being in vertically spaced relation. The free end of each arm carries a driven shaft journaled therein. The shafts are free floating and are disposed in vertically spaced relation with their axes in a common vertical plane. Each shaft carries a chamfering tool and a guide roller therefor arranged in close proximity. Biasing means yieldingly urges the free ends of the pivot arms towards each other so that their respective guide rollers and tools forcibly engage the top and bottom faces of a workpiece passed therebetween. The shafts are driven from a single motor common thereto, using pulley and elastic belt drive connections. A similar arrangement of pivot arms carries means for applying liquid stain to the surfaces chamfered by the tools.
