The batt has first and second sections, where each section is approximately one half the length of the batt. The apparatus comprises a lower conveyor for conveying folded batts in a first direction, and an upper conveyor which is positioned above the lower conveyor and move in the first direction to define a folded batt exit path. The apparatus further comprises a folding member for folding the insulation batt, where the folding member is adapted to contact the batt across its width. The folding member is mounted for movement to initially push the batt in a second direction, and then subsequently push the batt in the first direction, thereby pushing the batt along the folded batt exit path. The movement of the folding member folds the batt so that the first section of the folded batt is generally parallel to and contacting the second section. ## Claims ### Claim 1 An apparatus for folding a fibrous insulation batt, the batt having a length and a width, the batt having a first and second section, each section being approximately one half the length of the batt, the apparatus comprising: a. a lower conveyor for conveying folded batts in a first direction; b. an upper conveyor being positioned above the lower conveyor and moving in the first direction to define a folded batt exit path; c. a folding member for folding an insulation batt, the folding member including at least two contact elements to contact one side of the batt for dual folding, and the folding member mounted for movement to initially push the batt in a second direction, and then subsequently push the batt in the first direction, thereby pushing the batt along the folded batt exit path, wherein the movement of the folding member folds the batt so that the first section of the folded bait is generally parallel to and contacting the second section. ### Claim 2 (depends on 1) The apparatus of claim 1 in which the folding member is mounted for movement in an arcuate path. ### Claim 3 (depends on 1) The apparatus of claim 1 in which the folding member is a pivotally mounted arm having said at least two contact elements positioned on the arm for contacting and pushing the batt. ### Claim 4 (depends on 3) The apparatus of claim 3 in which the contact elements are retractably mounted on the arm to enable disengagement of the contact elements from the folded insulation batt after the batt has been pushed into the folded batt exit path. ### Claim 5 (depends on 1) The apparatus of claim 1 further comprising a curved support plate for supporting the first section of the insulation batt prior to folding. ### Claim 6 (depends on 1) The apparatus of claim 1 further comprising a deflector for rotating the first section of the batt around the upper conveyor to align the first section of the batt generally along the second direction. ### Claim 7 (depends on 6) The apparatus of claim 6 in which the deflector is pivotally attached to the folding member so that the movement of the folding member causes the deflector to rotate the first section of the batt around the upper conveyor to align the first section of the batt generally along the second direction. ### Claim 8 An apparatus for folding a fibrous insulation batt, the batt having a length and a width, the batt having a first and second section, each section being approximately one half the length of the batt, the apparatus comprising: a. a lower conveyor for conveying folded batts in a first direction; b. an upper conveyor being positioned above the lower conveyor and moving in the first direction to define a folded batt exit path; c. a folding member mounted for movement to push the batt into the folded batt exit path; and d. at least two contact elements retractably mounted on the folding member, the contact elements mounted to contact one side of the batt and between the first and second sections for dual folding where the movement of the folding member folds the batt so that the first section of the folded batt is generally parallel to and contacting the second section, and where the contact elements are retractable to enable disengagement of the contact elements from the folded batt after the batt has been pushed into the folded batt exit path. ### Claim 9 (depends on 8) The apparatus of claim 8 in which each contact element comprises a rod extending across the width of the insulation batt. ### Claim 10 (depends on 8) The apparatus of claim 8 in which the contact elements comprise a pair of rods extending partly across the width of the batt, each rod being retractable in opposite directions. ### Claim 11 (depends on 8) The apparatus of claim 8 further comprising a curved support plate for supporting the first section of the insulation batt prior to folding. ### Claim 12 (depends on 8) The apparatus of claim 8 further comprising a deflector for rotating the first section of the batt around the upper conveyor to assist in aligning the first section of the batt in a position which is generally parallel to the second section of the batt. ### Claim 13 (depends on 12) The apparatus of claim 12 in which the deflector is pivotally attached to the folding member so that movement of the folding member causes the deflector to rotate the first section of the batt around the upper conveyor to assist in aligning the first section of the batt in a position which is generally parallel to the second section of the batt. ### Claim 14 An apparatus for folding a fibrous insulation batt, the batt having a length and a width, the batt having a first and second section, each section being approximately one half the length of the batt, the apparatus comprising: a. a lower conveyor for conveying folded batts in a first direction; b. an upper conveyor being positioned above the lower conveyor and moving in the first direction to define a folded batt exit path; and c. a folding member mounted for movement to push the batt into the folded batt exit path; and d. first and second contact elements mounted on the folding member, the contact elements being spaced apart and mounted to contact one side of the batt and between the first and second sections, the movement of the folding member and the first and second contact elements creating two spaced apart folds across the width of the batt as the batt is being folded and pushed into the folded batt exit path so that the first section of the batt is generally parallel to and contacting the second section. ### Claim 15 (depends on 14) The apparatus of claim 14 in which the first and second contact elements are retractably mounted on the folding member to enable disengagement of the contact elements from the folded insulation batt after the batt has been pushed into the folded batt exit path. ### Claim 16 (depends on 14) The apparatus of claim 14 in which a distance between the contact elements is adjustable to accommodate different insulation batt thicknesses. ### Claim 17 (depends on 14) The apparatus of claim 14 in which the first and second contact elements each comprise a pair of rods extending partly across the width of the batt. ### Claim 18 (depends on 14) The apparatus of claim 14 further comprising a curved support plate for supporting the first section of the insulation batt prior to folding. ### Claim 19 (depends on 14) The apparatus of claim 14 further comprising a deflector for rotating the first section of the batt around the upper conveyor to assist in aligning the first section of the batt in a position which is generally parallel to the second section of the batt. ### Claim 20 (depends on 19) The apparatus of claim 19 in which the deflector is pivotally attached to the folding member so that movement of the folding member causes the deflector to rotate the first section of the batt around the upper conveyor to assist in aligning the first section of the batt in a position which is generally parallel to the second section of the batt.
