AVT, Inc., a manufacturer of automated retailing systems and custom vending machines, announced yesterday that it has filed for chapter 11 protection, according to a press release. AVT management states that the company's core vending and automated retailing business remains strong, and that the filing is related to past attempts at diversification into unrelated businesses. "We are convinced that the rehabilitative process of chapter 11 is the best way to protect our company and provide a path to future success," said Wayne Salvino, the newly installed president of AVT.
