Abstract
Subject invention provides method of arranging multilayer passive electronic components, enabling simple arranging of rolled thin foil from a roll on a supporting block in order to form a stack, where supporting, plastic foil with thin foil (63) in it is led from unrolling mechanism (67) for unrolling the foil, over the cross knife (66) and over two rotating side knives (68), through the pressing tool (65), over the separating crossbar (610) and pulling mechanism (612) to the rolling mechanism (611) for rolling of the supporting foil, from which the thin foil is already separated, where the supporting block (57) is put under the pressing tool (65). The invention also provides the supporting block.

Method of arranging multilayer passive electronic components, enabling simple arranging of rolled thin foil from a roll on a supporting block in order to form a stack, where supporting, plastic foil with thin foil (63) in it is led from unrolling mechanism (67) for unrolling the foil, over the cross knife (66) and over two rotating side knives (68), through the pressing tool (65), over the separating crossbar (610) and pulling mechanism (612) to the rolling mechanism (611) for rolling of the supporting foil, from which the thin foil is already separated, where the supporting block (57) is put under the pressing toll (65).
Method of centering of supporting blocks, which provides precise arrangement of layers, characterized in that, that on each working station said supporting block (57) is put on the fastening plate (56), where the supporting block is positioned and fastened by the means of two centering bolts (51, 52), each of them being guided in corresponding guiding element (53, 54), where the centering bolt (51) travels towards the supporting block (57) first, and sits into a corresponding centering groove (b), the movement of said centering bolt (51) being limited by a limitation element (55), and where after the movement of the centering bolt (51) is completed, the centering bolt (52) also travels toward the supporting block (57), so when both centering bolts (51, 52) sit in their corresponding centering grooves (b) the supporting block is centered and positioned, the supporting block (57) may be fastened onto a fastening plate (56) by the means of suction, which is enabled by at least one suction vertical hole (58) passing through the fastening plate (56), which enables fastening of the supporting block (57) onto a fastening plate (56), by the means of vacuum.
Method of longitudinal cutting of thin foil, characterized in that, that the supporting plastic foil (91) with thin foil (92) on it, is rolled on a roller (99) and under a straining weight (98) and over rotating side knives (68) led to a pulling mechanism (112), to the pulling mechanism (112), which pulls both foils in direction of arrow (Y), where the cutting rotating knife (68) with it's sharp edge touches the thin foil, and due to a force provided by a push bar (94), which is placed in a housing (97), sharp edge of the knife (68) cuts the thin foil (92) longitudinally.
Method of thin foil cross cutting, characterized in that, that supporting plastic foil (91) with thin foil (92) in it's lower side, is stretched over the cross knife (66), which is fastened on the machine housing, where the distance (x) between the thin foil (92) and the cross knife (66), enables undisturbed movement of the foil, and where the said method is implemented when the foil is not moving in such a manner that a cross-push bar (105) moves downward, bends the foil and presses it against the cutting edge of a cross knife (66), which cuts into and through the thin foil (92), while the supporting foil (91) remains uncut.
Supporting block (a), characterized in that, that it is in a form of metallic plate of perpendicular shape, with dimensions equal to or larger from dimensions of the stack, with two symmetrical wedge-shaped centering grooves (b) on of each of two opposite sides, where the top of each wedge-shaped groove (b) may be rounded up, and the angle (c) of said grooves (b) is between 15° and 1200, which provides reliable adjustment of centering bolt to a corresponding centering groove (b) and where said two grooves (b) enable centering of the supporting block (a) with said two centering bolts.
