Abstract
A banding machine for feeding sleeves of banding material onto bottle necks and the like when the sleeves are of tough material requiring use of a sharp cutting edge. The mandrel along which the tubular banding material is fed is formed to provide a radially outwardly opening groove at which the cutter cuts the material. The groove is closed when the mandrel and material are moved relatively.
Claims11
In a device for cutting bands from one end of an elongated length of tubular material,
- a housing,
- an elongated cylindrical mandrel supported in said housing and adapted to be received within said material,
- a casing carried by said housing,
- a rotor supported for orbital movement within said casing and provided with a circular radially inwardly directed cutting edge in surrounding relationship to said mandrel for cutting said material,
- said casing being provided with an end wall in a plane at right angles to the axis of said mandrel and extending across the upper side of said rotor,
- said end wall being free for movement by gravity into engagement with the upper side of said rotor to prevent shifting of the latter.
In a device for longitudinally feeding an elongated tubular member and cutting bands from one end of said member,
- a housing,
- an elongated mandrel vertically disposed in said housing and adapted to be axially received within said member,
- a casing,
- a rotor mounted in said casing and provided with a circular radially inwardly directed cutting edge surrounding said mandrel,
- a pair of opposed fingers mounted in said housing for movement toward each other into gripping relation with said member for feeding said member upon relative movement of said mandrel and housing,
- said fingers being adapted to engage said rotor at their corresponding ends for centering the latter relative to said mandrel when said fingers are out of gripping relation with said member.
In a device for longitudinally feeding an elongated tubular member and cutting bands from one end of said member,
- a housing,
- an elongated mandrel vertically disposed in said housing and adpated to be axially received within said member,
- a casing,
- a rotor mounted in said casing and provided with a circular radially inwardly directed cutting edge surrounding said mandrel,
- said casing including an upper sidewall supported for movement by gravity into engagement with said rotor for holding said rotor against shifting relative to said casing when said rotor is inoperative.
In a device for longitudinally feeding an elongated tubular member and cutting bands from one end of said member,
- a housing,
- an elongated mandrel vertically disposed in said housing and adapted to be axially received within said member,
- a casing,
- a rotor mounted in said casing and provided with a circular radially inwardly directed cutting edge surrounding said mandrel,
- pairs of upper and lower gripping elements respectively above and below said cutting edge for gripping said member during cutting of said member.
Apparatus for feeding a length of flexible tubular material downwardly along a vertical path of travel toward an article such as a bottle neck and for cutting said length into bands comprising:
- a housing,
- an axially elongated mandrel verically supported in said housing and adapted to be received within said tubular material for expanding the sidewalls of said material to tubular shape,
- a sleeve slidably supported on said mandrel for axial movement relative thereto,
- opposed annular shoulders on said mandrel and sleeve respectively, said shoulders adapted to be separated when said sleeve and mandrel are moved relatively in one direction to form a radially outwardly opening groove, and adapted to be abutted to close said groove when said mandrel and sleeve are moved relatively in the opposite direction by such article, and
- a cutter having an annular cutting edge surrounding said mandrel for cutting said material at said annular groove.
