Dumbjaw said:Is air-vac the model or the type of sweatband or what?
air vac would probably refer to their patented "A-hat press for producing corrugations at the inside of the front quarter of the crown adjacent to and extending into the under face of the brim... thus providing air passages into the crown for ventilation."
you see, what they did, was build a machine which "...comprises a base plate having a recess shaped to support a hat in an inverted position and a corrugating head. The head is mounted on double arms pivoted to the base and having a forwardly extending locking arm ending in a pivoted handle. The handle has a locking head which engages a recess in a keeper bar which is pivoted to a plate secured to the front of the base. Springs attached to the base urge the keeper bar forward at the top..."
it's all so simple really,
so who in the lounge has one of these machines at home?
