Description

In the manufacture of so-called folding bottoms of the lever.

boxes, d. H. of folding boxes with bottom The folding box blank 1, of a not

Closing flaps that come when opening the box cross-25 pointed insertion station, is from the Bänschnittes automatically form the bottom, 2 and 3 are guided against the lever 4 in the. While Folding box gluer special device round between the bands 2 and 3 guided part of the required that the bottom parts of the folding box folding box blank 1 in the same moving stone straighten up and lay down. It is also known that level continues, the bottom flap 1 ' for erecting the in the direction of movement from the lying 30 by the rising surface 5 of the lever 4 To use bottom parts folding hooks that in ben and in the further course of the forward movement Movement plane of the folding boxes from above against the stop 6 of the pawl 7 transported. the or protrude from below. by touching the front edge of the ground cover

The movement control of the upward and downward moving flap 1 'with the stop 6 (Fig. 2) emerges-folding hooks must be performed in time with the operation, 35 current force moves the pawl 7 by the amount in lever 4 so that the folding hooks into the pivot point 8 arranged between two cutting points under tension ten located gap fall and the leading edge compression spring 9, the pawl 7 from the effect Can reach under floor parts. Due to the area of the fixed ratchet stop 14 herdie is swiveled out at different throughput speeds. After the stop 6 of the and variable blank sizes requires a 40 pawl 7 from the leading edge of the bottom lock forced and intermittent movement control flap 1 'has been displaced, this pushes itself the folding hook has a high drive and control leading edge on the hold-down device 10 (Fig. 3), technical Effort, which also rend at the same time the kink 1 "of the folding chess the necessary adjustability of the device blank 1 touches the surface 5 of the lever 4, different types and sizes of cut 45 due to the straight forward movement of the fold as well as at different working speeds box blank 1 moves the kink 1 "in is increased. the lever 4 around the pivot point 11 in a known manner

The folding process initiated by the lever 4 of the is pressed without lifting the cut-to-be-erected part of the bottom flap 1 'can be completed, in which the folding box blank 1 through the belts 2 The invention is based on the object, which and 3 is transported on.

While previously the un-latch 7 fixed the lever 4. The device has the Locked lever only for light to medium-weight starting position for the next folding box to cardboard types a trouble-free run is guaranteed again.
