A progressive former having a bolster and a ram reciprocal towards and away from the bolster, a plurality of workstations evenly spaced across the bolster and ram including aligned tooling piece holders on the bolster and ram, cylindrical die cases in the tooling holders on the bolster and cylindrical tool cases in the tooling holders on the ram, the tooling cases at the workstations being coaxial, a sideways forming mechanism at one of said workstations, the mechanism including a cam and a cam follower radially outward of imaginary outward projections of the associated tooling cases, the cam follower being arranged to be activated by forward motion of the ram towards the bolster, the mechanism including a tool for forming the blank by applying a sideways force on the blank.

1. A progressive former having a bolster and a ram reciprocal towards and away from the bolster, a plurality of workstations spaced evenly along the bolster and ram including aligned tooling case holders on the bolster and ram, a sideways forming mechanism at one of said workstations, the sideways forming mechanism including a slide guided for movement perpendicular to a line between the tooling case holders at said one station, the slide being arranged to be activated by forward motion of the ram towards the bolster, the sideways forming mechanism including a tool for forming a blank by applying a sideways motion with the slide on the blank. 2. A progressive former having a bolster and a ram reciprocal towards and away from the bolster, a plurality of workstations spaced evenly along the bolster and ram including aligned tooling piece holders on the bolster and ram, cylindrical die cases in the tooling holders on the bolster and cylindrical tool cases in the tooling holders on the ram, the cylindrical die cases and tool cases at the workstations being coaxial, a sideways forming mechanism at one of said workstations, the sideways forming mechanism including a cam and a cam follower radially outward of an associated cylindrical tool case or die case, the cam follower being arranged to be activated by forward motion of the ram towards the bolster, the sideways forming mechanism including a tool for forming a blank by applying a sideways force on the blank. 3. A progressive former having a bolster and a ram reciprocal towards and away from the bolster, a plurality of workstations spaced evenly along the bolster and ram including die blocks on the bolster and tool holders on the ram, die cases in the die blocks on the bolster and cylindrical tool cases in the tool holders on the ram, the cylindrical tool cases and die cases at the workstations being coaxial, a sideways forming mechanism at one of said workstations, the die case at said one workstation being retractable into the die block and carrying a slide of said sideways forming mechanism, a cam operable to direct the slide towards an axis of the one workstation when the die case retracts into the die block in response to the ram approaching front dead center, the slide carrying a piercing tool effective to displace a slug from a wall of a blank located at said one workstation. 4. A progressive former as set forth in claim 3, wherein the cam is carried on the die block. 5. A progressive former as set forth in claim 3, wherein the slide carries a secondary slide and the cam is a double-faced element, a first face being arranged to displace the slide and a second face being arranged to displace the secondary slide in a direction opposite the direction that the first mentioned slide is directed. 6. A progressive former as set forth in claim 5, wherein blank gripping elements are arranged to grip said blank in the die case when the ram approaches front dead center. 7. A progressive former as set forth in claim 3, including a mandrel carried by the tool case at said one station, the mandrel being receivable within a tubular blank to support a cylindrical wall of the blank when the cylindrical wall is pierced by said piercing tool.
