Abstract
There is disclosed a board cutting machine in which a plurality of grooves are cut in a board such as a board of insulating duct material to permit the board to be folded into a multi-sided shape. As strips are cut from the board an extractor unit extracts the scrap strips and directs them to a chopping unit where the scrap is chopped into small pieces.
Claims6
A duct board cutting machine comprising,
- means for moving a board to be cut through the machine,
- cutting means including a plurality of blade supports selectively positioned across the machine,
- blade means on each blade support for cutting a strip from a duct board without cutting through the duct board and having a cutting edge which extends toward the board being cut and toward the strip being cut at a slight angle to a plane normal to the board, causing similarly angled cuts and cutting said strip free from the duct board,
- extractor means carried by each blade support lifting the cut strip from the board as it is being cut,
- at least one of the extractor means includes a deflector section carried by a blade means and a chute section carried directly by a blade support, and
- means chopping the strips into short sections.
