Abstract:
1. A stud handling system for studs having a shank and a radially projecting flange, comprising: a shank clamping device comprising a radially elastic shank clamping section having an internal bore with a diameter in a static state that is slightly larger than the shank of a stud for securely clamping the shank of a stud when a radially inward directed force is exerted on said shank clamping section; and a holding device for receiving a stud and holding it in a secure position for engagement by said shank clamping device, said holding device comprising: wherein a stud entering the insertion section of said collet with its radially projecting flange first and its shank projecting rearwardly therefrom passes into said secure position when the radially projecting flange of the stud is positioned in said securing groove; wherein said insertion section is further adapted to receive said shank clamping section of said shank clamping device, said shank claming section having an outer diameter in said static state greater than said first internal diameter (d); wherein said shank clamping device is adapted in a charging operation to move axially within said holding device to thereby move said stud from said secure position to a ready position wherein the radially projecting flange of the stud is located below said clamping lugs; and further wherein said securing lugs exert a radially inward acting force on the shank clamping section of said shank clamping device causing said shank clamping device to securely clam the shank of the stud during said charging operation.
