ABSTRACT:
Interposed between the cutting surface and the pressure head is a magnetic die holder including base and die carrying sections, the former being mounted on a telescoping member which is pivotally connected to the head for vertical movement therewith and which permits movement of the holder in a plane parallel to the cutting surface. The base and die carrying sections are connected by a spring to permit the die carrying section to be vertically displaced with respect to the base section for accurate positioning of the die relative to the cutting surface. The die carrying section is also rotatable relative to the base section to permit orientation of the die at any angle with respect to the cutting surface. The die carrying section includes an electromagnet which retains the die thereon. Also located on the die carrying section are a pair of handle grips, each having a switch mounted thereon, both of which must be simultaneously actuated in order to initiate vertical movement of the pressure head. By holding the grips, the die can be displaced and rotated relative to the base section to accurately position and orient the die, and the switches can be actuated. Thus, the die can be accurately positioned and successive die cutting cycles can be performed in a completely safe and highly productive manner without the necessity of the operator removing his hands from the grips.
