The punch force required to punch a piece of sheet metal can be estimated from the following equation: [4] F = 0.7 t L ( U T S ) {\displaystyle F=0.7tL(UTS)} Where t is the sheet metal thickness, L is the total length sheared (perimeter of the shape), and UTS is the ultimate tensile strength of the material.
A paper tape, constructed from punched cards, in use in a Jacquard loom. The large holes on each edge are sprocket holes, used to pull the paper tape through the loom. Perforated paper tapes were first used by Basile Bouchon in 1725 to control looms. However, the paper tapes were expensive to create, fragile, and difficult to repair.
The holes were then typically covered with paper or foil. After a patron bought a chance at the punchboard, he would puncture one of the hole's paper or foil covers with a nail and retrieve the ticket/gamepiece. If the gamepiece contained a winning number, the patron won the prize.
