Housing for holding a supply roll of large round bale wrap material

In a large round baler including a bale discharge gate, a bale wrapping mechanism mounted to said gate and including a wrap material roll housing including a support structure mounted to a rear portion of said gate, a wrap material roll support fixed to said support structure and including an upwardly and rearwardly inclined roll support surface for supporting a roll of wrap material within a dispensing zone adjacent the rear portion of the gate, a cover being pivotally mounted to the support for vertical pivotal movement about a horizontal transverse axis located adjacent an upper forward end thereof between a lowered, closed position enclosing said dispensing zone and a raised, open position permitting access to said dispensing zone, and at least one spring member connected between the support and the cover and biasing the latter such that it is held in its open position by the spring member, the improvement comprising:

• said housing including a brake member vertically pivotally mounted to said support for rotation about a second axis extending parallel to said transverse axis and having a crank arm connected to said spring member such that the brake member is biased into engagement with a roll of wrap material located in said dispensing zone when the cover is closed.

In a large round baler including support structure adjacent a bale-forming chamber, a bale wrapping mechanism mounted to the support structure and including a wrap material supply roll housing having an upwardly facing wrap material roll support surface and an upright roll abutment surface facing away from the chamber, said support and abutment surfaces being adapted for engaging the periphery of and supporting a roll of bale surface wrap material in a dispensing zone adjacent the chamber, the improvement comprising:

• said support surface including right- and left-hand roll end support surface sections forming part of right- and left-hand supports that are separated from each other to define a free space therebetween into which a roll of wrap material may extend when one end is loaded onto one of the support surface sections while the other end is supported adjacent to and at a level below the other one of the support surface sections;
• said support surface sections being inclined downwardly toward said chamber and said abutment surface;
• and each of said support surface sections being made of a corrosion resistant material.

In a large round baler including support structure adjacent a baler-forming chamber, a bale wrapping mechanism mounted to the support structure and including a wrap material supply roll housing having an upwardly facing wrap material support surface for supporting a roll of bale surface wrap material in a dispensing zone adjacent the chamber, the improvement comprising:

• said support surface including spaced apart, right- and left-hand roll end support surface sections forming the sole means for engaging an underside of the roll of surface wrap material and forming part of right- and left-hand roll end supports defining a free space therebetween for permitting the roll of surface wrap material to extend therethrough during loading when one end of the roll is placed on one of the roll end support surface sections while the other end of the roll is supported adjacent to but at a level below that of the other of the roll end support surface sections.
