Abstract: Apparatus is provided for dispensing tape for wrapping around insulation in roll form to hold the insulation in a compressed state. Machines are now known for forming elongate strips of insulation into tightly-wrapped packages. As the last portions of the strips are being wound, tapes are applied around the outer surfaces to hold the strips in the compressed, packaged state. Vapor barriers or backing sheets are sometimes applied to the outer surfaces of the insulating strips prior to the application of the tapes, or the tapes can be applied directly to the outer surfaces of the strips. In the latter instance, at least two tapes are employed for each package of insulation. The tapes are supplied by dispensers which are located adjacent a supply conveyor that feeds the insulating strips into the packaging machine. The new dispensers are designed to be located at substantially any position across the conveyor and the dispensers can also be located close together.
