摘要 One or more twig garlands are fed, cut and assembled to one end portion of a limb garland. The other end portion of the limb garland is bent by the machine at a suitable angle for entrance into an inclined hole in a tree trunk. The twig garlands are also bent by the machine smoothly, curvilineally and progresively throughout the lengths thereof after being cut and clipped to the limb garland.
权利要求
1. In a machine for making artificial tree branches from twig and limb garlands, feeding means for advancing at least one relatively long twig garland to a fastening station, means for swinging one end of a limb garland into said station and for bending said end into angular relation to the remainder of the limb garland and clipping means at said fastening station for fastening end portions of the garlands together.
2. The machine of claim 1, means for cutting said long twig garland and means for curvilineally bending the cut twig garland along the length thereof relatively to the limb garland.
3. The machine of claim 2, the twig garland bending means comprising a fixed convexly shaped element, a roller, and an oscillatory frame carrying the roller along a path sufficiently close to the surface of said element to exert bending pressure progressively along the length of said twig garland.
4. The machine of claim 2, the twig garland bending means comprising a roller, a fixed curved element arranged inwardly of the path of said roller and adapted to cooperate therewith, and means for swinging said roller about a pivot in spaced relation to the axis of said roller thereby to bend a twig garland projecting over said element between said element and said roller smoothly and progressively along the length of the twig garland and beyond the elastic limit thereof.
5. The machine of claim 1, the means for swinging and bending the limb garland comprising an oscillatory member having a blind hole therein, the hole being flared at the open end thereof, a pivot for said member, a fixed fulcrum adjacent said member and means for oscillating said member, said hole extending past said pivot in a direction away from said fulcrum.
6. The machine of claim 5, the means for advancing the twig garland arranging an end portion of the twig garland at the fastening station in overlapping relation to the end portion of the limb garland at said station, means for cutting the twig garland to length and means for curvilineally bending the cut twig garland.
7. The machine of claim 5, means for cutting the twig garland and means for shaping the cut twig garland comprising a roller, an oscillatory frame carrying the roller at one end of the frame, a shaft for and adjacent the other end of the frame, means for oscillating the shaft, a fixed generally convex shaping element arranged inwardly of the path of the roller and adapted to cooperate therewith to permanently bend into curvulinear form a twig garland projecting over said element and arranged between said element and said roller.
8. The machine of claim 4, the pivot for the roller swinging means being a shaft and rack and pinion means for oscillating said shaft, the means for swinging the limb garland comprising an oscillatory block, a pivot for and adjacent one end of the block, said block having a hole therein extending past the pivot in both directions for the reception of one end portion of the limb garland and a fixed stop member adjacent the block and in the path of the limb garland to halt movement in one direction of that part of the limb garland on one side of said pivot while the block continues to move the end portion of the limb garland held thereby and on the other side of said pivot thereby to bend said end portion, movement of the block in the other direction swinging the clipped and shaped branch out of the clipping means and into position for removal from the hole in the block.
9. In a machine for making artificial tree branches, positioning means for the end portions of relatively long twig garlands and of one end portion of a limb garland in overlapping relation, means for clipping together said overlapping end portions, means for receiving therein, for holding and for bending the other end portion of the limb garland into angular relation to the remainder of the limb garland, means for cutting the twig garlands to length and means for curvilineally bending the cut twig garlands throughout the lengths thereof.
10. The machine of claim 9, the clipping means clamping an encompassing fastener around the overlapping end portions of the garlands, the means for receiving holding and bending the end portion of the limb garland comprising a pivoted block having a hole therein and a fixed fulcrum member adjacent to and cooperating with said block, the means for bending the twig garlands comprising an oscillatory member exerting pressure upon and beyond the elastic limit of the twig garlands and a generally convex fixed anvil-like element cooperating with the oscillatory member and shaped correspondingly to the path given to said member.
