Abstract:
1. A machine for producing packaging cushioning, comprising: a. a first feed mechanism for successively feeding sheets of a substrate at a first speed, said first feed mechanism including a motor and a power supply therefor, wherein said motor is capable of drawing a varying amount of electricity from said power supply when said first feed mechanism feeds said sheets; b. a second feed mechanism for receiving said sheets from said first feed mechanism and feeding said sheets at a second speed; c. a control unit for controlling at least one of said first and second speeds to produce a desired degree of overlap between successive sheets; and d. a sensor to measure the amount of electricity drawn by said motor, said sensor being structured and arranged to generate a signal, which is indicative of the amount of electricity drawn by said motor, and communicate said signal to said control unit, wherein, said control unit is structured and arranged to modulate the amount of electricity that said motor draws from said power supply when said signal from said sensor has a value that is greater than or equal to a predetermined value.
