Method for bagging material
View Patent ↗The present invention provides an apparatus for bagging material into a film. The film has at least two overlapping sheets and at least one open edge. The apparatus a pair of spaced apart carriages and a pair of clamp assemblies movably mounted to a respective carriage. The clamp assemblies are pivotally movable relative to the respective carriage and vertically moveable along the length of the respective carriage. The clamp assemblies engage the film and open the film by separating the overlapping sheets. The clamp assemblies are moved downwardly along the length of the respective carriages so as to provide for the opened film to progressively bag material positioned thereunder. The clamp assembly includes a clamp having a pair of clamping members which are configured to grip a portion of the overlapping sheets for separation thereof. A method for bagging material into a film is also disclosed.
1. A method for bagging material into a stretchable film, said method comprising:
providing a desired length of stretchable film, said film having at least two overlapping sheets and at least one open edge;
stretching said desired length of film by clamping said film on the outer surface thereof at two opposite areas, each said area being near a respective longitudinal length of said film and moving said two clamped areas away from one another;
separating, subsequently to stretching said film, said two overlapping sheets by gripping an outer portion of each said sheet and moving said gripped outer portions away from one another thereby opening the film; and
covering the material by progressively moving said film onto the material while maintaining said gripped outer portions.
2. A method according to claim 1 , wherein said providing a desired length of film comprises unrolling a desired length of said film and cutting said desired length of said film.
3. A method according to claim 2 , wherein said cutting comprises sealing said overlapping sheets at a common longitudinal end.
4. A method according to claim 2 , wherein the edge of said film opposite said open edge is closed.
5. A method according to claim 2 , wherein the longitudinal ends of said film are sealed.
6. A method according to claim 1 , wherein said stretching further comprises moving said clamped film so as to position said open edge above the material.
7. A method according to claim 1 , wherein covering the material further comprises releasing said gripped outer portions.
