Abstract (en)
[origin: US4602472A] An apparatus and method is provided for packaging a fibrous, preferably compressible material; such as mineral fiber insulation shapes, in which the method and apparatus provides for delivering one or more such shapes (which are preferably rolls) through a staging area to a compression chamber in which they are compressed from a generally cylindrical shape or roll (or rolls) of a first diametral size, to a roll (or rolls) of a second, reduced diametral size, with the roll then being discharged from the compression chamber and being secured to substantially retain the cylindrical configuration of reduced diametral size, preferably by means of a sleeve or the like placed thereover. The operation occurs with a minimum of operator assistance, and may optionally be effected to occur automatically. The package formed may be of various roll lengths, and to this end, in the staging area prior to the compression chamber, the number of rolls that will be simultaneously compressed may be determined. Individual ones of the features are separately presented, such as the compression chamber, which employs a double stage compression, and a discharge arrangement that provides particular efficiency.
