Abstract

A rotary stamper includes an upper die plate assembly, a lower die plate assembly, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway while moving the lower die plate along a linear horizontal pathway. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods that extend from the lower die plate assembly up through the upper die plate. In operation, the lower die plate matches the horizontal movements of the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper die plate moves towards and away from the lower die plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.

IPC Classes  ?

• B21D 43/02 - Advancing work in relation to the stroke of the die or tool
• B21D 22/08 - Stamping using rigid devices or tools with die parts on rotating carriers
• B21D 28/36 - Perforating, i.e. punching holes using rotatable work or tool holders
• B23D 25/08 - Flying shearing machines having two coacting shearing blades mounted independently

Abstract

A formation and rotation apparatus for use in forming and rotating interconnected sections of a cylindrical workpiece, including a frame and a head arranged within the frame, the head defining two slots and being operatively rotated via an integral drive assembly. A first slide block is slidably disposed within one of the two slots, and a second slide block is disposed within another of the two slots, each of the first and the second slide blocks include a cutting wheel and a beading wheel for successively forming each of the interconnected sections. An armature having an axis of rotation is also provided, along with a gripping mechanism being operatively connected to the armature. A drive mechanism selectively rotates the armature about the axis of rotation after the gripping means has closed about one of the interconnected sections.

• B21C 37/12 - Making tubes or metal hoses with helically arranged seams
• B21C 37/28 - Making tube fittings for connecting pipes, e.g. U-pieces
• B25J 11/00 - Manipulators not otherwise provided for

Abstract

A ductmaking apparatus forms a laminate section including a sheet metal layer and a layer of insulation fastened to the sheet metal layer. The layer of insulation is severed from a moving web of insulation by pivoting slicing movement of a knife across the moving web.
