Definitions
- the present invention relates to an adjustable angle mechanism for a leather and/or synthetic materials crimping-blocking machine, being capable of providing vamp forming to a suitable usable fault-free shoe component, without the need for re-cutting, that is designed, manufactured and marketed by us exclusively for the first time.
- the oldest system in a general description in accordance with the prior art shown in figure 1 , consists of two metal plates (11), that clamp the piece of leather to be formed, and after that said piece of leather is forced through an adjustable opening (12), that stretches the material into the desired shape.
- the newer system in accordance with the prior art shown in figure 2 , is a flexible male mold, of various shapes and sizes (13), on which the piece of leather is placed and then this is pressed onto a mold (14), of a relevant form that gives said leather piece a bend shape.
- the newer system with the elastic mold although it is capable of producing a wrinkle free formed piece, it achieves very limited angles, while the nature of the pressing creates a lot of compression on the center of the piece, that rapidly decreases as we radiate towards the piece edges. Any effort to increase the final angle by pressure, results in stretching of the materials and wrinkles start to form, since the overstretching of the elastic mold causes excess elongation that results in deformations.
- This system is suitable for synthetic materials, also since it forms on a more female-male mold principle and not on a stretching principle, and although it is able to vary the angle of the formed piece by adjusting the pressing pressure, the maximum angles achieved are far for the desirable, and finally it is only able to handle simple geometries and unable to do the steep angles needed as the plates system can.
- the objective of the present invention is to overcome and eliminate all problems and disadvantages of the prior art mentioned above, by providing a new mechanism for leather and synthetic materials crimping - blocking, being capable of giving the materials the desired angles needed without irregular deformations, with said angles being adjustable, also being able to work with any kind of material, and to eliminate the need for after process trimming or ironing, as well as to press uniformly the whole material area.
- an adjustable angle mechanism for leather and/or synthetic materials crimping-blocking machine according to the appended independent claim 1.
- the present invention also provides a method of operating an adjustable angle mechanism for leather and/or synthetic materials crimping-blocking machine according to the appended claim 4.
- an adjustable angle mechanism for crimping - blocking machine with no deformation of leather and/or synthetic materials comprises of a main frame (9), a sub housing movable frame (10), a small traverse cylinder (7) of said sub housing movable frame (10), a main traverse and pressing cylinder (8), two properly attached on the movable sub frame bending cylinders (6) driving each one, a plate (5) that each pivots on a shaft (4), while on said plates (5) two sliding surfaces (3) are attached which house and lock in place a flexible male mold (2), said mechanism characterized in that, when activated and pressed against a fixed female mold (1), due to its overall design is capable of copying the shape of said fixed female mold (1), in a male-female manner.
- said mechanism is capable of achieving many different angles, by means of controlling the bending cylinders (6) independently, without the need of changing the molds, it also works with any kind of material and eliminates the need for after process trimming or ironing, and furthermore uniformly the whole material area, for when a piece of material is placed on the flexible male mold (2), the two traverse cylinders (7,8) are activated in sequence and then the bending cylinders (6), causing said flexible male mold (2) to bend in two arcs front and back, copying said fixed female mold (1), thus shaping and evenly pressing the overall area of the processed material, and during the circular movement said sliding surfaces (6), control the elongation of said flexible male mold (2), keeping it in check since they can slide on said rocker plates (5), thus achieving the required motion without elongation movement of said flexible male mold (2).
