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).
