A packaging machine () includes a machine foundation () and a variable-width belt system (). The variable-width belt system () is moved relative to the packaging machine and configured to establish a belt pocket (). A product is admitted into the belt pocket and rolled onto itself to establish a rolled product () as the belt moves relative to the machine foundation ().

Packaging machine with variable-width belt system

A frangible fiberglass insulation batt includes a pair of fiberglass strips arranged to lie in side-by-side relation to one another and a frangible polymerized binder bridge spanning a gap between the fiberglass strips and retaining the fiberglass strips in side-by-side relation. To produce such a batt, a stream of uncured fiberglass insulation is cut along its length to form two side-by-side fiberglass strips and then passed through a curing oven to cause heat generated in the oven to polymerize (cure) binder associated with the strips in the gap to form the frangible polymerized binder bridge.

Frangible fiberglass insulation batts

A frangible fiberglass insulation batt includes a frangible plane defined by a series of cuts in the batt.

A frangible fiberglass insulation batt includes a pair of fiberglass strips arranged to lie in side-by-side relation to one another and a frangible adhesive bridge spanning a gap between the fiberglass strips and retaining the fiberglass strips in side-by-side relation. To produce such a batt, a fiberglass insulation blanket is cut along its length to form two side-by-side fiberglass strips and then an adhesive material is applied to form a frangible adhesive bridge between the strips.

This invention relates to a pipe insulation product which, as contrasted to presently available commercial products, eliminates fishmouthing of the protective liner from the insulation blanket, eliminates cutting the liner at the job, always a difficult task, is extremely easy to manufacture, ship and handle, and is very easy to use in the field, even under adverse working conditions such as high winds.
