Wrapping apparatus

A method of wrapping an object with stretch film by winding turns of stretched film about the object, wherein the rate at which stretched film is dispensed is proportional to the rate at which turns of film are wound around the object, and wherein a power-stretch film dispenser is used, which has a plurality of driven rollers rotatable at different surface speeds for drawing film from a supply, for stretching it and for dispensing the stretched film, either the dispenser or the object is supported for rotation and is driven rotationally relative to the other by a drive means having a power take-off point, for winding turns of film dispensed by the dispenser about the object, the drive means being connected to at least one of the dispenser rollers via a direct mechanical drive transmission for rotating the roller, whereby the speed of the drive means controls the speed of at least one of the dispenser rollers.

Wrapping apparatus for winding stretch film about an object, comprising a powered stretch film dispenser having a plurality of driven rollers rotatable at different surface speeds for stretching film while drawing it from a supply, and for dispensing the stretched film, means to support one of the object and the dispenser rotationally relative to the other, to enable stretched film dispensed by the dispenser to be wrapped round and round the object, a drive means or motor to rotate the rotationally-supported one of the object and the dispenser, the drive means being connected to at least one of the dispenser rollers via a direct mechanical drive transmission for rotating the rollers, whereby the speed of the drive means controls the speed of at least one of the dispenser rollers, whereby said drive means or motor provides motive power both for rotating the rotationally-supported one of the dispenser and the object and for driving the driven rollers, whereby in use the rate at which stretched film is dispensed is kept proportional to the rate at which turns of film are wound around the object.

A method of wrapping an object with stretched film by winding turns of said film around the object, wherein the rate at which turns of film are wrapped around the object is kept proportional to the rate at which the film is dispensed from a supply thereof;

• wherein a powered stretch film dispenser is used, the dispenser having a plurality of driven rollers rotatable at different surface speeds, for stretching film while drawing it from the supply, and for dispensing the stretched film;
• wherein one of the dispenser and the object is rotated relative to the other by a drive means having a power take-off point so that stretched film dispensed by the dispenser is wrapped round and round the object, the drive means being connected to at least one of the dispenser rollers via a direct mechanical drive transmission for rotating the rollers, whereby the speed of the drive means controls the speed of at least one of the dispenser rollers.
