Claim:
Carrier strip ( 1 ) for nails ( 3 ) or other securing elements equipped with a head ( 15 ) and tip ( 16 ), in which the carrier strip ( 1 ) comprises a series of cartridges ( 2 ) arranged in series and successively interlinked, whereby each cartridge ( 2 ) holds a nail ( 3 ) or securing element, and where the cartridge ( 2 ) consists of a central body ( 4 ) arranged around a central longitudinal axis ( 18 ) perpendicular to the direction of the carrier strip ( 1 ), whereby the central body ( 4 ) is finished off on its upper side by a cover or crown ( 7 ) and on its lower side by another cover or base ( 6 ), whereby the crown ( 7 ) and the base ( 6 ) are concentric to the central body ( 4 ) and have a greater surface area, where both the crown ( 7 ) and the central body ( 4 ) and the base ( 6 ) are crossed by a central passage gap ( 8 ), centred with respect to the longitudinal axis ( 18 ), inside which is the nail ( 3 ), being the carrier strip ( 1 ) characterized in that: the base ( 6 ) and the crown ( 7 ) are divided into a non-conical area ( 21 , 20 ), and a conical area ( 14 , 19 ), whereby the conical area ( 14 , 19 ) is closest to the central body ( 4 ), in such a way that the conical area ( 14 , 19 ) serves as a transition area between the central body ( 4 ) and the non-conical area ( 21 , 20 ) of the crown ( 7 ) or base ( 6 ), the height (H 2 ) of the crown ( 7 ) is lower than the height (H 1 ) of the base ( 6 ), the cartridge ( 2 ) includes at least two lateral reinforcement pillars ( 5 ), arranged parallel to the longitudinal axis ( 18 ) of the cartridge ( 2 ), which connect the crown ( 7 ) to the base ( 6 ) without coming into contact with the central body ( 4 ) of the cartridge ( 2 ), the opening of the central passage gap ( 8 ) on the external surface of the crown ( 7 ), or surface which is nearest to the head ( 15 ) of the nail ( 3 ) when introduced into the cartridge ( 2 ), is tapered, in the central body ( 4 ) of the cartridge ( 2 ) at least two windows ( 11 ) or openings are made on a plane parallel to the longitudinal axis ( 18 ) of the cartridge ( 2 ), whereby these windows ( 11 ) are diametrically opposite with respect to the longitudinal axis ( 18 ), in such a way that they are opposite each other, giving the impression of a passage gap.
