Abstract
The invention proposes a staple-forming apparatus which is intended for stapling machines for forming staples and may be designed to be smaller than prior-art apparatuses. This is achieved according to the invention in that a locking bar (9) for locking a pusher in the forming apparatus during the operation of forming the staple is fitted in a moveable manner in the pusher and a fixed stop (13) for the locking bar (9) is provided on the housing (2) of the staple-forming apparatus.
Claims12
Staple-forming apparatus for stapling machines for forming staples in stapling heads, having a housing in which a pusher is mounted in a displaceable manner, said pusher serving, at the same time, as a stop during the staple-forming operation and as an ejecting element during stapling of material which is to be stapled, such as paper, cardboard or the like, and a means which locks the pusher in relation to the housing being provided, characterized in that a locking bar is fitted in a moveable manner in the pusher (3) and a fixed stop (13) for the locking bar (9) is provided on the housing (2) of the staple-forming apparatus (1).
Apparatus according to one of the preceding claims, characterized in that a slot guide (10) for the locking bar (9) is provided in the housing (2).
Apparatus according to one of the preceding claims, characterized in that the slot (10) has at least two sections (11, 13) of different widths.
Apparatus according to one of the preceding claims, characterized in that the locking bar (9) has at least two sections with different diameters.
Apparatus according to one of the preceding claims, characterized in that the slot (10) has a stepped formation (14) at least in certain regions.
Apparatus according to one of the preceding claims, characterized in that a restoring element (18) is provided.
Apparatus according to one of the preceding claims, characterized in that the restoring element is a helical spring (18) which is arranged between a stop (19) on the locking bar and a stop (17) on the pusher.
Apparatus according to one of the preceding claims, characterized in that a blocking member (21) can be fastened on the locking bar (9) by a rotary closure.
Apparatus according to one of the preceding claims, characterized in that the blocking member (21) has a rotation-prevention means.
Apparatus according to one of the preceding claims, characterized in that a rotation-prevention means 20 [sic] is provided on the locking bar (9).
Stapling head for use in a stapling machine for stapling material which is to be stapled, such as paper, cardboard or the like, characterized in that a staple-forming apparatus according to one of the preceding claims is provided.
