Abstract

Wrapping apparatus for use with a baling machine of the type having a forming chamber in which a round bale is formed and into which a wrapping material is fed to wrap the bale, includes a housing, a feeding device mounted on the housing for feeding a wrapping material from a source of wrapping material to the forming chamber, and a drive on the housing having a drive position for driving the feeding device, the drive being biased into a non-drive position so that the drive is disengaged from driving the feeding device. A cutter is provided for cutting the wrapping material after the wrapping material exits the feeding device, the cutter being movable between a first and a second position. A pivotal lever is operable between an initial position and a first operable position, the pivotal lever being movable from the initial position to the first operable position to actuate the drive from its non-drive to its drive position to thereby drive the feeding device to feed the wrapping material. The cutter is movable from the first position to the second position as the pivotal lever is moved from its initial position to the second operable position, and a cutter release is operable to release the cutter from the second position so that the cutter moves to the first position and in so moving cuts the wrapping material, the cutter release being adjustable to release the cutter after a pre-set number of revolutions of the round bale.

Wrapping apparatus for use with a baling machine of the type having a forming chamber in which a round bale is formed and into which a wrapping material is fed to wrap said bale, comprising a housing means, feeding means mounted on said housing means for feeding a wrapping material from a source of wrapping material to said forming chamber, drive means mounted on said housing for movement between a non-drive position and a drive position for driving said feeding means, biasing means between said drive means and said housing means for biasing said drive means into said non-drive position wherein said drive means is disengaged from driving said feeding means, cutter means pivotably mounted on said drive means for cutting said wrapping material after the wrapping material exits said feeding means, said cutter means being pivotable between a cutting position and a non-cutting position in which said cutter means is clear of the wrapping material exiting from said feeding means, a pivotal lever means connected to said drive means and movable between an initial position and at least one operable position, said pivotal lever means being movable from said initial position to said operable position to move said drive means from its non-drive to its drive position to thereby cause said drive means to drive said feeding means to feed said wrapping material, cutter actuating means mounted on said drive means and connected to said pivotal lever means such that said pivotal lever means in moving from said initial position to said at least one operable position pivots said cutter means from said cutting position to the non-cutting position, means for moving said cutting means to said cutting position, meter means operably connected to said cutter actuating means for retaining said cutter means in said non-cutting position while metering an adjustable predetermined amount of wrapping material fed to wrap said bale, said pivotable lever means being movable by an operator from said initial position to said at least one operable position to pivot said cutter means to said non-cutting position and to actuate said meter means to retain said cutter means in the non-cutting position while metering a metered amount of wrapping material fed to wrap said bale, said metering means having means to actuate said means for moving the cutter means to said cutting position after said metered amount has been metered and when said material has been fed into the pressing chamber and into contact with the bale to thereby release said retention of said cutter means so that the cutter means moves to the cutting position and in so doing cuts off said metered amount of wrapping material.

Wrapping apparatus for use with a baling machine of the type having a forming chamber in which a round bale is formed and into which a wrapping material is fed to wrap said bale, comprising a housing means, feeding means mounted on said housing means for feeding a wrapping material from a source of wrapping material to said forming chamber, drive means mounted on said housing for movement between a non-drive position and a drive position for driving said feeding means, biasing means between said drive means and said housing means for biasing said drive means into said non-drive position wherein said drive means is disengaged from driving said feeding means, cutter means pivotably mounted on said drive means for cutting said wrapping material after the wrapping material exits said feeding means, said cutter means being pivotable between a cutting position and noncutting positions in which said cutter means is clear of the wrapping material exiting from said feeding means, a pivotal lever means connected to said drive means and movable between an initial position, an operable position, and an intermediate position between said initial position and said operable position, said pivotal lever means being manually movable from said initial position to said operable position to move said drive means from its non-drive to its drive position to thereby cause said drive means to drive said feeding means to feed said wrapping material, cutter actuating means mounted on said drive means and connected to said pivotal lever means such that said pivotal lever means in moving from said initial position to said operable position pivots said cutter means from said cutting position to a non-cutting position, means for moving said cutting means to said cutting positions, meter means operably connected to said cutter actuating means for retaining said cutter means in said non-cutting position while metering the amount of wrapping material fed to wrap said bale, said biasing means moving said pivotable lever means from said operable position to said intermediate position and biasing said drive means to a non-drive position, means connecting said lever means in its intermediate position to said meter means for actuating said metering means so that said metering means retains said cutter means in the non-cutting position while metering a metered amount of wrapping material fed to wrap said bale, said metering means having means to actuate said means for moving the cutter means after said metered amount of wrapping material has been metered to thereby release said retention of said cutter means from said non-cutting position so that the cutter means moves to said cutting position and in so doing cuts off said metered amount of wrapping material.
