Abstract
A method for the production of a multilayer capacitor block. Two superposed metallized films are carried by an entraining caterpillar track into a cavity in such a manner as to form a stack of successive folds. In a first operation, the horizontal displacement of a support performs a transverse compression of the stack, and the displacement of a movable bar performs a vertical compression of the stack. The stack thus compressed is then coated with molten metal by spraying, in such a manner as to form an elementary block.

A method for the production of a multilayer capacitor block comprising the steps of:
- (a) unwinding the feeding, into a cavity, at least one metallized film which forms a succession of alternately insulating and conductive layers comprising laterally offset metallisations;
- (b) at least partially filling the cavity with said film, under at least the action of gravity, in such a manner so as to form a stack comprising successive folds along a longitudinal direction and in contact with two sides of the cavity situated in a first lateral direction, the lateral edges of the said metalized film being situated in a second lateral direction;
- (c) compressing the stacked successive folds along the longitudinal direction;
- (d) compressing the stacked successive folds along the first lateral direction;
- and
- (e) equipping the block with electrical connections.
A method for the production of a multilayer capacitor block comprising the steps of:
- (a) feeding, into a cavity defined by at least one pair of relatively movable support members, at least one metalized film of the type having alternately disposed insulating and conducting layers and laterally-offset metalizations so as to form a stack of said film comprising multiple successive folds;
- (b) moving one of said pair of support members relative to the other of said pair of support members to reduce a first dimension of said defined cavity to thereby responsively compress said stack in a first direction;
- and
- (c) reducing a second dimension of said defined cavity, different from said first dimension, to responsively compress said stack in a second direction which is different from said first direction.
A method of producing a multilayer capacitor block comprising the steps of:
- (a) feeding, into a cavity having predetermined lateral and longitudinal dimensions, at least one metalized film of the type having alternately disposed insulating and conducting layer and laterally offset metalizations;
- (b) allowing said film to at least partially fill said cavity to form a stack of said film therein comprising multiple successive folds;
- (c) reducing the longitudinal dimension of said cavity to responsively compress said stack in the longitudinal direction;
- and
- (d) reducing the lateral dimension of said cavity to responsively compress said stack in the lateral direction.
