is pivotable about a pivot point 21 and includes an idle i e not powered roller 22 signature drive rollers 24 are arranged before the deceleration brake 17 and propel the signature 4 at a fast speed for example at 255 inches sec the roller 23 is driven at a slower angular velocity such that the signature 4 is slowed for example to about 90 inches sec when the solenoid 19 is actuated the idle roller assembly 20 pivots clockwise about its pivot point 21 such that a signature 4 is sandwiched between idle roller 22 and roller 23 thus the signature 4 is decelerated the stopping brake 18 also includes a solenoid 19 which is mechanically coupled with a brake pad 25 the solenoid 19 is actuated by a controller not shown when the solenoid is actuated a signature 4 between the brake pad 25 and the table surface 1 is stopped fig9 also illustrates an example of sensors 26 that may be used with the present invention the sensors 26 include a light emitting element 28 such as a light emitting diode and a photodetector 27 fig1 a and 10b are a side view and an end view respectively of a refined embodiment of a deceleration roller 17 39 of the present invention an idle roller 22 is held in a housing 33 the housing 33 is pivotable about pivot 30 a release solenoid 19a is arranged above the housing 33 on a side of the pivot 30 opposite to the idle roller 22 a deceleration solenoid 19b is arranged above the housing 33 on the same side of the pivot 30 as the idle roller 22 the solenoids 19a and 19b are provided with input signals from a controller.
