Abstract
ABSTRACT
It is a simple device by means of which top quality folding of laps, as well as of reinforcements of card-board boxes, is obtained.
It consists of a base (1), to which a bottom sup-port (4) provided with an adjustable screw (5) is con-nected, to which an open chain (6), whose free end is linked to a slipper (8), movable by a guide-shaft (9), in which a push spring (10) of the slipper (8) and tension spring of the chain (6) have been mounted, is connected.
The guide-shaft (9) is connected to a rear body (11) which is joined to a main support (12) interlocked to an opera-ting tree (13) of the entire mechanism.
With this arrangement, upon the tree (13) rotating 180°, a reinforcement column will be formed from a lap (15), previously provided with the precise folding lines and pushed by the slipper (8.)

Description
-- 208~681 CARDBOARD BOXES
OBJECT OF THE INVENTION
Justas is expressed in the title of this specifica-S tion, the present invention refers to a mechanism for lapfolding and reinforcement forming in cardboard boxes. It is an extremely simple device, for which reason its opera-tion turns out to be really effective in the old~ng and reinforcement of laps.
The operation is produced by means of rotating a tree, to which among other elements, a slipper which in principle pushes, directly on the lap forming the rein-forcement of a box, is linked.
BACKGROUND OF THE INVENTION
Presently, different devices to carry out the fold~
ing of laps and forming of reinforcement columns in card-board boxes are known. Such devices include some pneuma-tic cylinders that act upon some elements that will turn the degrees necessary to effect the folding of the cor-responding laps. At times the operation thereof entails some difficulties as far as the finish of the folds and reinforcement columns is concerned, since neither of them are optimal, but rather they have some defects.
On the other hand, these devices are comprised of numerous elements, therefore, they are excessively com-plex.
DESCRIPTION OF THE INVENTION
In order to overcome the problems mentioned in the above section, a mechanism for lap folding and reinforce-ment folding in cardboard boxes has been designed. It ; constitutes the object of the invention. It provides some relevant features over conventional devices and ~ its structure and operation are very simple.
- It comprises a base, to which a bottom support pro-~ ~5 vided with an adjustable screw, to which an open chain , :
~ .
: :
, ~8~
1 is hooked, is connected. The free end of the chain is linked to a slipper movable along a guide-shaft, in which a spring that pushes said slipper forward upon tightening the chain, has been mounted. The guide-shaft is connect-ed to a rear body, which is joined to a main body inter-locked with an operating tree of the entire mechanism.
With this arrangement, the mechanism of the invention remains inoperative when the chain and spring are not tightened, the slipper in the most forward area and the lap to be folded is straight, with the previously pre-marked folding lines. Afterwards, when the mechanism begins to operate, the tree rotates 180Q in order to form the reinforcement column. In this process, the slipper pushes, in the first place, a lap until a first fold there-of is made, the chain and the spring becoming tightened,at the same time that the slipper moves backward. When the complete rotation of 180Q is produced, the spring tightens as much as possible and so does the chain, the slipper moving totally backward, at the same time that the outer part of the lap presses against the correspond-ing side wall of the box.
The entire mechanism returns to the inoperative posi-tion thanks to the spring, in the moment when the tree causing all the movements remains freed.
Hereinafter in order to provide a better understand-ing of this specification and as an integral part thereof, a series of figures in which the object of the invention has been represented with an illustrative and non-restric-tive manner, is attached hereto.

Figure 3.- It is a view of the mechanism of the invention, where the totally formed box reinforcement is shown, said mechanism having rotated entirely, in other words 180Q.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Making reference to the numbering used in the figures, the mechanism for lap folding and reinforcement forming in cardboard boxes, has an extremely simple structure, at the same time that its operation is very simple. With this device notable quality of the folding and forming of reinforcements in cardboard boxes is achieved.
It is comprised from a base (1), connected to a sup-port plate (2) of a side wall (3) of the box, a bottom support (4) that includes an adjustable screw (5), to which the end of an open chain (6) is anchored, is coupled, the free end of the chain connecting to an intermediate ele-ment (7) linked to a slipper (8), movable along a guide-shaft (9), in which a spring (10) that pushes said slip-per ~8) forward when the chain is tightened due to the spring itself, has been mounted. Said guide-shaft (9) is connected to a rear body (11) which is joined to a main support (12) interlocked to a tree (13), through which the entire mechanism is operated. The slipper (8) in-cludes on its innermost end a projection or stop ~14), which will advantageously contact in the first place, with the outside part of the lap (15) forming the rein-forcement column, when the latter is made.
Observing figures 1, 2 and 3, in this order,we see that in the first one, the device of the invention -' is in the inoperative position; chain (6) and spring (10) are not tightened, the slipper (8) is in the most forward area and the lap (15) of cardboard to be folded, for~ing a .

In the second figure, the tree (13) has rotated 90, as well as the slipper (8), which in its forward movement has effected an intermediate folding of the lap (15) cor-responding to line (17.) In this situation, chain (6) and spring (10) have been tightened, ensuring the stable posi-tion of the slipper (8) that has moved backward a bit, al-ways carried on the guide-shaft (9.) The first contact point of the slipper (8) on lap (15) is done advantageously, as it has already been said above, by means of a small stop (14) that will press near the free edge of the lap (15), thus producing the start of lS said intermediate folding.
Now in figure 3, a totally perfectly formed reinforce-ment triangular column corresponding to one of the corners of the box appears. In order to go from the intermediate position of figure 2 to the final position of figure 3, the tree (13) has rotated 90 in the same direction as before, whereby the slipper (8) has moved even further backward, the same pressing on the outer part of the lap that remains abutted against the corresponding side wall (3) of the box.
An intermediate support (19) for the seat of the tightened chain (6) just as the different positions are occupied as the tree (13) rotates, which moves the mecha-nism of the invention.
