two belt system at this point in the progression the pin 22 of the first belt pair 7 u2032 is acting to decelerate the signature 24 in fig4 c at time t 0 022 seconds there is depicted the state of the two belt system of fig2 at point 45 of the graph of fig3 a next pin 33 on the accelerating second belt pair 12 rotates around idler sprocket 43 into the path of a next incoming signature 32 while the pin 22 of the first belt pair 7 u2032 continues to decelerate the corresponding signature 24 the signature 25 previously abutting the pin 23 in fig4 b is transported away from the two belt system at a fully decelerated speed meanwhile the pin 23 of the second belt pair 12 continues to be accelerated by the motor 11 in fig4 d at point 46 of the graph of fig3 the pin 33 of the second pair of belts 12 is positioned ahead of the incoming signature 32 finally in fig4 e the second pair of belts 12 continues to be accelerated until the pin 33 has engaged the signature 32 point 19 of the graph of fig3 thereafter the second belt pair 12 starts to decelerate at the same time the first pair of belts 7 u2032 is fully decelerated point 18 of the graph of fig3 as is the.
