Title: Portable batt cutter

Abstract: A portable batt cutter custom cuts standard width, continuous, extended length fibrous insulation blankets at a construction site to form batts with specific dimensions corresponding to the dimensions of the structural framework cavities to be insulated. The portable batt cutter includes storage for retaining a fibrous insulation blanket; a feed mechanism for feeding the fibrous insulation blanket from the storage to a transverse cutter; and the transverse cutter which makes a transverse cut across the width of the fibrous insulation blanket to determine the length of the batt. The portable batt cutter may also include a cutter for making a longitudinal cut in the fibrous insulation blanket to form a batt having a width less than the width of the fibrous insulation blanket and a measuring device to measure the length of the batt prior to forming the transverse cut in the fibrous insulation blanket. The portable batt cutter has a size and weight enabling the cutter to be readily moved from construction site to construction site.
