Abstract
Abstract A carrier strip supports a plurality of nails for use in an explosive powder charge operated setting device. The nails are equidistantly spaced apart and held in bores in the strip. Guidance members, placed on the nail shanks, hold the nails within the strip bores. The heads of the nails project outwardly from one side of the carrier strip. The outside diameter of the nail heads is not greater than the inside diameter of the strip bores, so that the nails can be pushed through the bores out of the carrier strip into a receiving material.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
Carrier strip for elements to be driven into a receiving material by an explosive powder charge operated setting device, said carrier strip being elongated and having two pair of opposite sides extending in the elongated direction, one said pair of opposite sides comprising a first side and a second side disposed in spaced relation, a second said pair comprising two third sides disposed in spaced relation and extending between said first and second sides, said carrier strip having bores extending between said first and second sides and each said bore having a bore surface with an inside diameter, axially extending nails disposed in spaced relation and displaceably supported in said bores, each said nail has a head at one end and a shank extending axially from the head, at least one guidance member located on each said shank of said nails and extending radially outwardly therefrom into engagement with the bore surface for holding and supporting said nails in said strip, said heads of said nails having an outside diameter not greater than the inside diameter of sid bore surface, wherein the improvement comprises that said head projects axially outwardly from the first side of said strip.
Claim 2
Dependent Claim
197 words
Carrier strip for elements to be driven into a receiving material by an explosive powder charge operated setting device, said carrier strip being elongated and having two pair of opposite sides extending in the elongated direction, one said pair of opposite sides comprising a first side and a second side disposed in spaced relation, a second said pair comprising two third sides disposed in spaced relation and extending between said first and second sides, said carrier strip having bores extending between said first and second sides and each said bore having a bore surface with an inside diameter, axially extending nails disposed in spaced relation and displaceably supported in said bores, each said nail has a head at one end and a shank extending axially from the head, at least one guidance member located on each said shank of said nails and extending radially outwardly therefrom into engagement with the bore surface for holding and supporting said nails in said strip, said heads of said nails having an outside diameter not greater than the inside diameter of sid bore surface, wherein the improvement comprises that said head projects axially outwardly from the first side of said strip.
Claim 3
Dependent Claim
43 words
Carrier strip, as set forth in claim 1, wherein at least the heads of said nails project outwardly from the first side of said carrier strip with said guidance member on each said nail located ajdacent to said first side of said strip.
Claim 4
Dependent Claim
34 words
Carrier strip, as set forth in claim 2, wherein another said guidance member located on each said shank adjacent said second side of said carrier strip and spaced from the one said guidance member.
Claim 5
Dependent Claim
32 words
Carrier strip, as set forth in claim 1, wherein said guidance member is disk-shaped and has a flat conical configuration tapering inwardly from the bore surface toward said head of said nail.
Claim 6
Dependent Claim
38 words
Carrier strip, as set forth in claim 1, wherein said nail head is cylindrically shaped and has a diameter greater than the diameter of said shank with a section tapering inwardly from said cylindrical section to said shank.
Claim 7
Dependent Claim
33 words
Carrier strip, as set forth in claim 1, wherein said third sides of said strip have projections extending outwardly therefrom with said projections located aligned on opposite sides of each of said bores.
Claim 8
Dependent Claim
25 words
Carrier strip, as set forth in claim 6, wherein said projections have a square cross section viewed in the elongated direction of said carrier strip.
Claim 9
Dependent Claim
