Abstract
Abstract A bundling device for rods having a hollow mandrel through which the rods are passed and which mandrel has prongs that are provided with steps. The steps carry elastic rings which are removed from the prongs onto the rods by a stripper. The stripper consists of a tubular member that surrounds the prongs and which has protrusions for engaging the rings and stepwise moving the rings along and off the steps of the mandrel as relative movement is created between the stripper and the prongs.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
107 words
Apparatus for bundling rods, tubes, sections, or the like, comprising: means for assembling the rods, tubes, or sections into a pile-like bundle; a hollow mandrel including axially extending prongs being provided with steps and mounted for radial movement and displacement relative to each other, the steps carrying expanded elastic rings; means for providing the radial displacement of said prongs; means for passing the bundle through the mandrel; and a tubular member disposed for movement relative to the mandrel and having protrusions for engaging the rings and stepwise moving the rings along and off the steps of the mandrel to be seated onto the bundle as passing through.
Claim 2
Dependent Claim
107 words
Apparatus for bundling rods, tubes, sections, or the like, comprising: means for assembling the rods, tubes, or sections into a pile-like bundle; a hollow mandrel including axially extending prongs being provided with steps and mounted for radial movement and displacement relative to each other, the steps carrying expanded elastic rings; means for providing the radial displacement of said prongs; means for passing the bundle through the mandrel; and a tubular member disposed for movement relative to the mandrel and having protrusions for engaging the rings and stepwise moving the rings along and off the steps of the mandrel to be seated onto the bundle as passing through.
Claim 3
Dependent Claim
105 words
Apparatus for bundling elongated stock such as rods, tubes, sections, or the like, comprising: means for assembling the stock into a pile like bundle; a plurality of prongs mounted around an axis and for radial displacement, the prongs having steps for holding expanded rings; and a tubular stripper concentrically surrounding the prongs and having steps to move the rings in steps down on the steps of the prongs and one by one off the prongs; means for passing the bundle coaxially through the prongs so that the rings are clampingly seated one by one onto and around the bundle as stripped off by the stripper.
Claim 4
Dependent Claim
105 words
Apparatus for bundling elongated stock such as rods, tubes, sections, or the like, comprising: means for assembling the stock into a pile like bundle; a plurality of prongs mounted around an axis and for radial displacement, the prongs having steps for holding expanded rings; and a tubular stripper concentrically surrounding the prongs and having steps to move the rings in steps down on the steps of the prongs and one by one off the prongs; means for passing the bundle coaxially through the prongs so that the rings are clampingly seated one by one onto and around the bundle as stripped off by the stripper.
Claim 5
Dependent Claim
47 words
Apparatus as in claim 2, said prongs being mounted on segments having pins, an annular disk with oblong slots extending at an angle to a radius for guiding the pins to thereby move the segments and the prongs radially; and means for mounting the disk for rotation.
