[78-L] 1923 Columbia Demonstration Record Sleeve

[Dave Burnham]

I was going to message that I have no idea how they MADE laminated pressings and have always wondered about this, but as I started to type, it suddenly hit me; they must have had precut 10 inch and 12 inch centre cores so when they pressed a record, they put the label in the press, then a biscuit of the soft music surface, then the core, then another biscuit and another label. The pressure would distribute the soft material evenly over the core and "voila", a new record. If that IS how it was done then I'm curious to know - did this require special presses or could normal presses handle this?
