Spread roll cap system

A harvester comprising:

• a pair of oppositely facing sidewalls attached to a frame or a subframe of the harvester;
• at least one material spread roll, positioned transversely between the pair of sidewalls and about a rotational axis, the at least one material spread roll comprising:
• (i) a roll tube comprising an exterior surface, a longitudinal length and at least one face on at least one end of the longitudinal length, said face defining a width of the roll tube;
• (ii) at least one cap positioned over or proximate to the at least one face of the roll tube, said at least one cap comprising a base portion and a pin portion;
• and
• (iii) at least one bearing mechanism comprising a bearing and a flange;
• wherein the base portion of the at least one cap comprises oppositely positioned inner and outer surfaces laterally positioned relative to the roll tube and oppositely a contiguous ring surface axially positioned relative to the roll tube;
• wherein the pin portion of the at least one cap comprises an outer surface and is longitudinally positioned around the rotational axis;
• wherein the inner surface of the base portion of the at least one cap covers, is adjacent to, or is proximate to the at least one face of the roll tube;
• and
• wherein the bearing is positioned around the pin portion of the at least one cap and the flange is mechanically linked to at least one sidewall of the pair of sidewalls.

A method of wrapping a bale, comprising:

• (a) loading a roll of wrapping material onto a material support cylinder;
• (b) dispensing wrapping material from the roll of wrapping material onto a material spread cylinder, the material spread cylinder comprising a roll tube;
• (c) spreading the wrapping material across the length of the material spread cylinder by the rotation of the material spread cylinder around an axis, such that the wrapping material is capable of completely covering the width of the bale;
• (d) simultaneous with (c), preventing the wrapping material from reaching at least one bearing positioned at the ends of the material spread cylinder by at least one cap positioned at the ends of the material spread cylinder;
• (e) dispensing the spread wrapping material from the material spread cylinder to the bale in a bale chamber, such that the spread wrapping material is capable of wrapping the bale.
