Suction-type inserter for picking up and transporting non-rigid sheets

In an inserter for picking, transportation and depositing of non-rigid sheet-like or folded material one at a time from a material bundle to a depositing station, the improvement comprising:

• at least one reciprocatingly movable suction head (912,913) mounted relative to said material bundle so as to be operable at a given level, and being reciprocatingly movable in only one plane from a first position in said one plane above said material bundle but proximal to that end part of said material bundle located nearest to a depositing station to a second position in said one plane at said depositing station and back again to said first position for transport of said material;
• means for imparting said reciprocating movement to said at least one reciprocatingly movable suction head (912,913) in said only one plane;
• at least one prelifter (914,915) having a suction head and being mounted adjacent said material bundle to pick up at least the end portion of one material at a time from said material bundle to move at least said end portion of the picked-up material to said given level at which said at least one reciprocatingly movable suction head (912) operates;
• and
• said suction head of said at least one prelifter meeting said at least one reciprocatingly movable suction head at said given level and at said first position at the same time.
