Nip system in a module wrap feed arrangement

A persistent nip system for use with an associated wrap floor assembly that is movable between lowered and raised positions relative to a chassis supporting a module builder of an associated harvester, the nip system comprising:

• a plurality of wrap frame roller members connected with a frame structure of the associated wrap floor assembly, wherein the plurality of wrap frame roller members are movable together with the associated wrap floor assembly between the lowered and raised positions relative to the chassis of the associated harvester;
• and
• a plurality of chassis roller members biased relative to the chassis of the associated harvester towards the associated wrap floor assembly,
• wherein the plurality of wrap frame roller members are connected with the frame structure at a position relative to the plurality of chassis roller members causing persistent nips to be formed:
• between the plurality of chassis roller members and the plurality of wrap frame roller members for the associated wrap floor assembly being disposed in the lowered position relative to the chassis;
• between the plurality of chassis roller members and associated wrap floor belts of the associated wrap floor assembly for the associated wrap floor assembly being disposed in the raised position relative to the chassis;
• and
• between the plurality of chassis roller members and a combination of the plurality of wrap frame roller members and the associated wrap floor belts for the associated wrap floor assembly being disposed at a transition conformation between the lowered and raised positions relative to the chassis of the associated harvester.

A method of retrofitting an associated harvester having wrap floor assembly that is movable between lowered and raised positions relative to a chassis supporting a module builder to provide a nip system in the associated harvester, the method comprising:

• providing a plurality of wrap frame roller members;
• and
• connecting the plurality of wrap frame roller members with a frame structure of the associated wrap floor assembly to be movable together with the associated wrap floor assembly and at a position relative to a plurality of chassis roller members biased relative to the chassis of the associated harvester towards the associated wrap floor assembly to cause nips to thereby be formed:
• between the plurality of chassis roller members and the plurality of wrap frame roller members for the associated wrap floor assembly being disposed in the lowered position relative to the chassis;
• and
• between the plurality of chassis roller members and associated wrap floor belts of the associated wrap floor assembly for the associated wrap floor assembly being disposed in the raised position relative to the chassis.
