Abstract
ABSTRACT OF THE DISCLOSURE:
A unitary holding strip made of plastics material for retaining a plurality of screws in a row, the screws having longitudinal axes and a threading with a given outer thread diameter, which unitary holding strip includes a plurality of screw holding sleeves and lands interconnecting the sleeves which extend along a portion of the threaded length of the respective screw in the axial direction thereof and comprise inwardly facing screw threads for receiving the screw threading.
The unitary holding strip of the invention is characterized in that the sleeves completely surround the screw threading and are formed with longitudinally aligned perforations along one side thereof, substantially between the lands, defining an area of reduced strength such that a screw which is being threaded into a work-piece is automatically separated from its sleeve while simul-taneously maintaining the length of the strip substantially intact and while guiding the screw by the inwardly facing screw threads of the respective sleeve.

Description
:
~s~
The present lnven-tion relates to improvements in a , unitary holding strip made of plastics material for retaining a plurality of screws in a row, of the type described in Canadian application No. 245,738 filed February 13, 1976 (inventors: Keusch et al). ~uch unitary holding strip includes a plurality of screw holding sleeves and lands interconnecting the sleeves which extend along a portion of the threaded length of the respective screw in the axial direction thereof, the lands and sleeves having a wall thickness substantially smaller than the outer thread diameter of the screws. The sleeves comprise inwardly facing screw threads for receiving the screw threading and along one side thereof, substantially between the lands, an area of reduced strength such that a screw which is being threadedVinto a workpiece is automa-i . .
tically separated from its sleeve while simultaneously maintaining ~ the length of the strip substantially intact and while guiding the `
`r screw by ~he inwardly facing threads of the respective sleeve.
The presence of the inwardly facing screw threads in the sleeves provides the advantage that during screwing-in a screw . :
,` can be positively guided until it has penetrated at least partly into the workpiece and is then guided by the latter. When the head ~; of the screw reaches a weakened wall area of the sleeve, the latter is forced apart or is split so that the screw can leave it easily.
The empty strip can then leave the screw driving tool without broken remnants remaining to clog the tool or damage the surface of the workpiece. In addition, the prior strip gave the advantage of higher production speed at lower cost.
It is an object of the present invention to form a weakened wall area of the sleeve in such a way that the sleeve holds a screw securely, guides it reliably during a screwing-in operation, and ensures its ready release even in cases where, due to poor production conditions during extrusion of plastics material ` onto a row of screws, variations occur in the formation ofthe sleeves.

According to the invention therefore there is provided a unitary holding strip made of plas-tics material for retaining a plurality of screws in a row, the screws having longitudinal axes and a threading with a given outer thread diameter, which unitary holding strip includes a plurality of screw holding sleeves and lands interconnecting the sleeves which extend along a portion :
of the threaded length of the respective screw in the axial direction thereof and comprise inwardly facing screw threads for receiving the screw threading. The unitary holding strip of .-the invention is characterized in that the sleeves completely surroundthe screw threading and are formed with longitudinally ~', aligned perforations along one side thereof, substantially between the lands, defining an area of reduced strength such that a screw .
which is being threaded into a workpiece is automatically . separated from its sleeve while simultaneously maintaining the length of the strip substantially intact and while guiding the screw by the inwardly facing screw threads of the respective . sleeve. .
The perforations may be formed by providing strap-like wall portions in each sleeve. The advantages of the invention ; are thus retained even if, due to poor production conditions during extrusion of plastics material onto a row of screws, variations occur in the formation of the sleeves.
A preferred embodiment of the invention will now be :.
. described in greater detail with reference to the appended drawings, in which:
Figure 1 is a side view of part of a screw strip according to the invention;
. Figure 2 shows a cross section along line II-II of . , . 30 Figure l; and :
: Figure 3 shows a cross section along line III~III of ... Figure 1.

.~ 3 , Referring to the drawing, Figure 1 shows part of a screw strip 1, the parallel screws of which each have a shank 3, a screw thread 4 and a head 5. To hold the screws 2 there is a holding strip 6 of elastic plastics material which extends perpendicularly to the axes of the screws. However, the strip can also be slightly inclined to the axes of the screws in a screw strip in which the screws are off-set from each other.
Each screw thread is encircled by a sleeve 7 in the strip 6 over part of its circumference, the rest of the circumference being secured by strap-like wall portions 8 which are integral with the sleeve 7. The strip 6 therefore has a weakened wall area ;
9 on one side, in that the sleeve 7 has perforations 10 formed by the strap-like wall portions 8.
The mating thread 11 formed on the inside of each sleeve 7 mates with the screw thread 4. Further, the sleeves 7 are connected together by lands 12 which are integral with them, the lands 12 being arranged in the median plane o~ the strip 6. On :
one side of the strip each land 12 has a rib 13 and the ribs extend along the entire length of the strip 6.
The screw strips 1 shown in Figures 1 and 3 have a part at their right-hand outer end where the screw 2 has already been released from the sleeve 7. The portions 8 have been burst apart, but still remain connected to the rest of the sleeve 7 so that the empty strip 6 can leave the screw-driving tool through a suitable opening.
