Abstract (en)
A cushioning conversion machine and method for converting sheet stock material into a three dimensional strip of cushioning are disclosed. The conversion machine includes a conversion assembly and a stock supply assembly. The conversion assembly draws sheet stock material from a stock supply roll whereby the stock supply roll is rotated, and converts the stock material into a three dimensional strip of cushioning. The stock supply assembly supports the stock supply roll (11) and includes a braking assembly (72) movable between a brake engaged position and a brake disengaged position. In the brake engaged position, a braking force is imparted to the stock supply roll to prevent the stok supply roll from rotating. In the brake disengaged position, the braking force is removed from the stock supply roll thereby permitting the stock supply roll to rotate. The braking assembly is biased to the brake engaged position by a biasing member and is urged to the brake disengaged position by a force overcoming the bias.
