The invention relates to a conveyor for elongate components (12) designed with a head and a shank. The conveyor comprises a feed arrangement (7). The feed arrangement (7) comprises a transfer arrangement (8) with a transfer region (15) in which a component (12) can be positioned. In the transfer region (15), a feed duct (11) having a head guiding duct (13) and a shank guiding duct (14) passes into a conveying duct (16). The transfer arrangement (8) comprises at least one catch unit (17). The catch unit (17) comprises at least one catch element (18). The catch element (18) is arranged opposite the head guiding duct (13) and penetrates at least partially therein. It can be deflected from the head guiding duct (13) against a spring force.

What is claimed is: 1. A method of operating a rivet machine, the method comprising: (a) pneumatically feeding a rivet along an elongated feeding duct, at least a section of the feeding duct having an open and substantially T-shaped cross section; (b) contacting an enlarged head of the rivet with an elongated element of the machine while the rivet travels along the duct; (c) pivoting an end of the element away from a rivet feed path in the duct to allow the rivet to pass; (d) locating the rivet in a position aligned with a plunger, after step (c); (e) moving two elongated positioning segments, located adjacent the plunger, to engage the rivet; and (f) advancing the plunger to drive the rivet past the positioning segments. 2. The method of claim 1 further comprising moving the rivet in a direction substantially perpendicular to a plunger-advancing direction, as the rivet moves past the element. 3. The method of claim 1 further comprising outwardly expanding a split sleeve, co-axially aligned with the plunger, as the rivet is driven through the sleeve by the plunger. 4. The method of claim 1 further comprising spring biasing the element toward the rivet feed path. 5. The method of claim 1 further comprising rotating the element about a fixed pivot pin. 6. The method of claim 1 further comprising preventing the rivet from reverse traveling up the duct by abutting the head of the rivet with an end of the element, after the rivet has moved past the element. 7. The method of claim 1 further comprising spring biasing and pivoting the positioning segments toward a central axis of the plunger. 8. The method of claim 1 wherein the rivet is a self-punching rivet including the head with is solid, and a hollow shank adjacent an open, leading end. 9. A method of rivet feeding, the method comprising: (a) feeding a rivet along a feeding duct; (b) rotating a beam about a pivot pin from a feeding duct-intruding orientation to a retracted orientation; (c) abutting an end of the beam against the rivet after the rivet has moved past the beam, to deter reverse movement of the rivet; and (d) inwardly moving segments toward each other, each segment including a rivet-engaging recess, to temporarily hold the rivet adjacent an end of the duct. 10. The method of claim 9 wherein at least a majority of each of the segments is located on a plunger-side of a line defined by a surface of the duct facing an open end of the rivet, where the duct is adjacent the segments. 11. The method of claim 9 wherein each of the segments is elongated in a direction substantially parallel with a feeding direction of the duct, adjacent the segments. 12. The method of claim 9 further comprising moving the rivet in a direction substantially perpendicular to a plunger-advancing direction, as the rivet moves past the beam. 13. The method of claim 9 further comprising: (a) advancing a plunger to drive the rivet out of a riveting machine; and (b) outwardly expanding a split sleeve, co-axially aligned with the plunger, as the rivet is driven through the sleeve by the plunger. 14. The method of claim 9 wherein the rivet is a self-punching rivet including a head which is solid, and a hollow shank adjacent an open, leading end. 15. A method of manufacturing using a riveting machine, the method comprising: (a) pneumatically moving a rivet past a catch element in a direction substantially perpendicular to a plunger-advancing direction; (b) pushing the catch element to open a movement path through contact of the rivet with the catch element; (c) temporarily holding the rivet in rivet-receiving recesses adjacent an end of a plunger; and (d) preventing the rivet from moving in reverse back past the catch element due to movement of the catch element to a substantially blocking position. 16. The method of claim 15 further comprising rotating elongated segments to temporarily hold the rivet adjacent the end of the plunger, each of the segments including the rivet-receiving recess. 17. The method of claim 15 further comprising: (a) advancing a plunger to drive the rivet out of a riveting machine; and (b) outwardly expanding a split sleeve, co-axially aligned with the plunger, as the rivet is driven through the sleeve by the plunger. 18. The method of claim 15 further comprising spring biasing the catch element toward the rivet. 19. The method of claim 15 wherein the catch element is an elongated beam which is pivotable about a fixed pivot pin. 20. The method of claim 15 wherein the catch element is a substantially L-shaped member made of a resilient material. 21. The method of claim 15 wherein the rivet is a self-punching rivet including a head which is solid, and a hollow shank adjacent an open, leading end. 22. The method of claim 15 further comprising moving the rivet through an elongated feeding duct including a substantially T-cross sectionally shaped internal passage. 23. A method of operating a rivet machine, the method comprising: (a) feeding a self-punching rivet along an elongated feeding duct, at least a section of the feeding duct including a substantially T-shaped cross sectional internal passage; (b) rotating a catch into the passage of the duct by a spring; (c) contacting the rivet against the catch to control movement of the rivet; (d) holding the rivet in a position aligned with an elongated plunger, and aligned with an adjacent end of the duct; and (e) linearly advancing the rivet through an inwardly biased open end portion of the rivet machine, spaced away from a portion performing step (d), by movement of the plunger. 24. The method of claim 23 further comprising rotating elongated segments to temporarily hold the rivet adjacent the end of the plunger, each of the segments including a recess. 25. The method of claim 23 wherein the catch is an elongated beam which is pivotable about a fixed pivot pin. 26. The method of claim 23 further comprising moving the rivet in a direction substantially perpendicular to a plunger-advancing direction as the rivet moves past the catch. 27. The method of claim 23 wherein the catch comprises means for decelerating the self-punching rivet and the open end portion comprises sleeve means for maintaining the orientation of the self-punching rivet during advancing movement. 28. A method of riveting, the method comprising: (a) feeding a rivet along an elongated feeding duct; (b) inwardly rotating positioning segments toward a centerline of an elongated plunger, the segments each being elongated in a direction substantially perpendicular to the centerline; (c) holding the rivet adjacent an end of the duct and aligned with the centerline of the plunger; and (d) driving the rivet with the plunger after step (c). 29. The method of claim 28 further comprising moving a catch located in the duct to decelerate the rivet. 30. The method of claim 28 further comprising biasing the segments toward the centerline of the plunger. 31. The method of claim 28 further comprising holding the rivet in a recess in each of the segments. 32. The method of claim 28 wherein at least a majority of each of the segments is located on a plunger-side of a line defined by a surface of the duct facing an open end of the rivet, where the duct is adjacent the segments. 33. The method of claim 28 wherein the rivet is a self-punching rivet.
