Abstract
An apparatus for clamping packaging material may include a packaging material holder. The packaging material holder may include a first jaw, a second jaw, opposing the first jaw, and a jaw opening between the first and second jaws. The jaw opening may be configured to receive a portion of packaging material. The packaging material holder may include an inflatable structure configured to fill at least a portion of the opening. The apparatus also may include a packaging material insertion tool configured to insert the portion of packaging material into the jaw opening for clamping.
Claims18
An apparatus for clamping a leading end of a length of packaging material to be wrapped on a load, the apparatus comprising:
- a packaging material dispenser for dispensing packaging material to the load;
- and
- a packaging material holder, the packaging material holder comprising:
- a first jaw;
- a second jaw disposed opposite the first jaw;
- the first and second jaws fixed relative to each other and defining an opening therebetween for receiving the packaging material extending between the packaging material dispenser and the packaging material holder;
- first and second opposing surfaces disposed within the opening between the first and second jaws;
- and
- at least one inflatable element within the opening and defining at least one of the first and second opposing surfaces;
- the at least one inflatable element convertible between a first, unpressurized condition defining a gap within the opening, and a second, pressurized condition closing the gap to thereby bring the first and second opposing surfaces in contact with one another, wherein the at least one inflatable element is configured to, when in the second, pressurized condition, clamp the packaging material in the opening between the first and second opposing surfaces when the packaging material is received in the opening.
An apparatus for clamping a leading end of a length of packaging material to be wrapped on a load, the apparatus comprising:
- a packaging material holder, the packaging material holder comprising:
- a first jaw;
- a second jaw disposed opposite the first jaw;
- the first and second jaws defining an opening therebetween;
- and
- at least one inflatable element within the opening;
- the inflatable element convertible between a first, unpressurized condition defining a gap within the opening, and a second, pressurized condition closing the gap to thereby clamp the packaging material in the opening;
- and
- a support assembly configured to moveably support the packaging material holder, wherein the support assembly includes a rotatable support arm configured to rotate the packaging material holder toward and away from the load about an axis that is substantially parallel to an axis of rotation for wrapping the load.
