Abstract
Abstract A device for connecting steel cord web sections, consisting of steel cord webs having steel threads disposed in a longitudinal direction, to form a steel cord web with steel threads disposed at an angle to the longitudinal direction of the original steel cord web. This device comprises a conveyor belt means having a plurality of narrow belts for feeding the steel cord web sections and retaining means for clamping the seam portions of the steel cord web sections to be connected. Also included are means for bringing together and joining, at a connecting point, the connection faces of the seam portions of the steel cord sections to be connected. The improvement of this invention lies in the conveyor belt means comprising an incoming conveyor belt having an upper section extending beneath the connection point and an outgoing conveyor belt having a plurality of narrow belts spaced with respect to one another for advancing the steel cord web which is produced. The outgoing conveyor belt extends beneath the connection point where the incoming conveyor belt and the outgoing conveyor belt interlock with one another beneath the connection point. Also, retaining means is positioned above the conveyor belt means.

Claim 1
Independent Claim
322 words
In a device for connecting steel cord web sections, of steel cord webs having steel threads disposed in the longitudinal direction, to form a steel cord web with steel threads disposed at an angle to the longitudinal direction of the original steel cord web, said device comprising: a conveyor belt means having a plurality of narrow belts for feeding the steel cord web sections; retaining means for clamping the seam portions of the steel cord web sections to be connected; and means for bringing together and joining, at a connecting point, the connection faces of the same portions of the steel cord sections to be connected; the improvement wherein the conveyor belt means comprises an incoming conveyor belt having an upper section extending beneath the connection point, an outgoing conveyor belt having a plurality of narrow belts spaced with respect to one another for advancing the steel cord web which is produced, the outgoing conveyor belt extending beneath the connection point; wherein the incoming conveyor belt and the outgoing conveyor belt interlock with one another beneath the connection point; and wherein the retaining means is positioned above the conveyor belt means, said retaining means comprising incoming and outgoing pusher belts having a plurality of narrow belts spaced with respect to one another, the incoming pusher belt and the outgoing pusher belt interlocking with one another above the connection point, said device further including drive means for driving said conveyor belt means wherein the incoming conveyor belt and the incoming pusher belt and the outgoing conveyor belt and the outgoing pusher belt are drivable in pairs, said pairs being drivable in synchronism, and the size of the gap between the conveyor belt means and the retaining means cooperating therewith is determined by the thickness of the steel cord web section or the steel cord web such that the web section and web are clamped between the conveyor belt means and the retaining means.

In a device for connecting steel cord web sections, of steel cord webs having steel threads disposed in the longitudinal direction, to form a steel cord web with steel threads disposed at an angle to the longitudinal direction of the original steel cord web, said device comprising: a conveyor belt means having a plurality of narrow belts for feeding the steel cord web sections; retaining means for clamping the seam portions of the steel cord web sections to be connected; and means for bringing together and joining, at a connecting point, the connection faces of the same portions of the steel cord sections to be connected; the improvement wherein the conveyor belt means comprises an incoming conveyor belt having an upper section extending beneath the connection point, an outgoing conveyor belt having a plurality of narrow belts spaced with respect to one another for advancing the steel cord web which is produced, the outgoing conveyor belt extending beneath the connection point; wherein the incoming conveyor belt and the outgoing conveyor belt interlock with one another beneath the connection point; and wherein the retaining means is positioned above the conveyor belt means, said retaining means comprising incoming and outgoing pusher belts having a plurality of narrow belts spaced with respect to one another, the incoming pusher belt and the outgoing pusher belt interlocking with one another above the connection point, said device further including drive means for driving said conveyor belt means wherein the incoming conveyor belt and the incoming pusher belt and the outgoing conveyor belt and the outgoing pusher belt are drivable in pairs, said pairs being drivable in synchronism, and the size of the gap between the conveyor belt means and the retaining means cooperating therewith is determined by the thickness of the steel cord web section or the steel cord web such that the web section and web are clamped between the conveyor belt means and the retaining means.
Claim 3
Dependent Claim
50 words
A device as claimed in claim 1 including a feeder belt having a plurality of narrow belts provided within the incoming conveyor belt and driven synchronously therewith, wherein the narrow belts of the feeder belt are disposed in the intermediate spaces between the narrow belts of the incoming conveyor belt.
Claim 4
Dependent Claim
47 words
A device as claimed in claim 1 including a plurality of freely rotatable discs having a width equal to the width of the narrow belts, said discs being positioned at the connection point wherein said conveyor belt means and said retaining means are mounted on said discs.
Claim 5
Dependent Claim
28 words
A device as claimed in claim 1 including deflecting means for deflecting said conveyor belt means and said retaining means at said connection point from a common plane.
Claim 6
Dependent Claim
48 words
A device as claimed in claim 4 including axes adjustably disposed in a direction perpendicular to the common plane of the conveyor belt means, and at least one pressure means for raising and lower the axes to deflect and return the conveyor belt means and the retaining means.
