Abstract: Apparatus for packaging fibrous insulation batts comprises means for compressing a stack of batts, a bagger for bagging the batts, and means for moving the stack of compressed batts into the bagger, where the bagger comprises upper and lower spouts which have a curvature approximating the curvature of the completed bag of batts.

Abstract: A fibrous insulation batt packaging machine comprises a vacuum chamber, an inlet tube for receiving batts, the inlet tube being defined by (a) a pair of sidewalls, (b) a pair of moveable end walls, and (c) a platen, the platen being mounted for vertical movement, vacuum means for partially evacuating the vacuum chamber thereby causing compression of the batts, vacuum chamber top doors mounted for movement to close the inlet tube, means for moving the platen vertically upward to further compress the batts, means for moving the moveable end walls to open the inlet tube, and pushing means for pushing the compressed batts from the vacuum chamber into a bag.

Abstract: Apparatus for delivering fibrous insulation batts comprises an upstream batt receiving section and a downstream batt delivering station, the upstream batt receiving station being adapted for two modes of operation, the first mode being for folding batts and delivering folded batts to the downstream batt delivering station and the second mode for delivering unfolded batts to the downstream batt delivering station, the upstream batt receiving station comprising a conveyor belt for transporting batts through the upstream batt receiving station, a plurality of rolls for guiding the conveyor belt along a first path in the first mode of operation, means for moving at least one of the rolls to guide the conveyor belt along a second path for the second mode of operation, a support member spaced apart from the conveyor, thereby defining a gap between the conveyor belt in the first mode of operation and the support member, the support member being adapted to support a portion of the batt as it is transported off the do

Abstract: The method comprises cutting a glass wool blanket with a circular cutting grid having elastomeric plugs in the grid spaces. The cut columns and the plugs are both compressed. The cut columns are ejected by expansion of the plugs.

Abstract: Apparatus is provided for packaging strips of flexible, compressible material, such as layers of glass fibers. The compressible strip is wound under compression into a roll by the apparatus to provide a compact package. The compressed package can then be held in that state by tapes or the like which are automatically fed into contact with a trailing end portion of the compressible strip as it is being rolled up. The packaging apparatus includes a generally horizontal conveyor which carries the strip along a generally horizontal path. An upright, back-up belt conveyor is positioned to intercept the strip in its path and to deflect the forward edge of the strip upwardly away from the path. An infeed or guide roll helps to guide the forward edge of the strip toward the upright conveyor and a compression or tuck roll helps to turn the forward edge back downwardly after it is directed upwardly by the belt conveyor and to cause the strip to begin to roll into a spiral package.

Abstract: Matted fibrous material is fed between a rotatable shaft having a chopping blade mounted thereon and a rubber-covered back-up roll cooperable with the blade. Clutch and brake means enable the blade shaft to be rotated intermittently through one turn to chop off a selected length of material. An upper portion of the back-up roll is above the plane of support of feed and discharge conveyors on opposite sides of the back-up roll, and a cam on the blade shaft compresses the material before it is chopped by the blade.
