Abstract
Apparatus for trimming small booklet-like products transported by bands (16) between a position serving for front trimming and a position serving for foot and head trimming. The bands (16) include a pair of transport bands (18,20) guided about a respective main deflecting roll (24) at their ends facing an insertion region (22). A synchronously-drivable auxiliary transport band (26) extends beyond the main transport bands (18,20) toward the insertion region (22) and is guided about an auxiliary deflection roll (28) at its end facing the insertion region (22). The diameter (d) of the auxiliary roll (28) is less than 1/3 the diameter (D) of the main deflection roll (24).
Claims32
Apparatus for transporting a product bound in a booklet-like manner so that a bound-spine end may be inserted into a cutting mechanism and be transported therethrough, said apparatus comprising:
- a transport means for transporting said product between a first position serving for front trimming and a second position serving for foot-and-head trimming, the transport means including at least one pair of main transport bands guided about a main deflection roll located adjacent said cutting mechanism;
- and,
- at least one synchronously drivable auxiliary-transport band guided about an auxiliary drive that is connected to said main deflection roll about an auxiliary deflection roll that is located closer to said cutting mechanism than said main deflection roll, the diameter of said auxiliary deflection roll being less than the diameter of said main deflection roll.
