A safety device for use on a press brake for forming a part between a die mounted on a lower frame of the press brake and a punch mounted on a moveable ram of the press brake. The safety device includes a gate pivotably mounted to the ram and a sensor mounted to the gate. The gate is pivotable between a guarded position and a retracted position, wherein the gate is in the guarded position when the punch is more than a preselected distance from the die, and wherein the gate is in the retracted position when the punch is less than the preselected distance from the die. The sensor is electrically connected to the press brake to suspend operation of the press brake upon actuation of the sensor when the gate is in the guarded position.

A coated roller for transportation and stretching of plastic film web during load unitization, and a process for preparation of the coated roller. A cylindrical metallic roller core is pitted by blasting, then primed, heated and immersed in a room-temperature liquid plastisol comprising vinyl particles dissolved in a plasticizer. The plastisol accumulates on the hot metal to a depth determined by immersion time. After removal, curing and cooling the coated core is machined by lathe to expose a cellular infrastructure and achieve a cylindrical coating coaxial with the core. The coated roller exhibits superior durability, resistance to tackifier additive buildup, and resistance to circumferential web slippage during web stretch between two rollers in a film path from a supply roll to a load being wrapped.
