Abstract: The present invention generally encompasses a device for removing waste material from a blank. The invention includes a rotatable stripping pin housing and a stationary cam. The stripping pin housing includes a number of radially extending grooves in its axial surface. Each groove terminates at an aperture located in the stripping pin housing's circumferential surface. A stripping pin apparatus having an radially outwardly extending stripping pin capable of penetrating waste material and an axially extending cam follower is position within each groove. Each cam follower is engaged within a cam track in the stationary cam. The stripping pin housing is placed so that the stripping pins will engage waste material (and not the blank) as the material passes the device. Thereafter, the stripping pin housing is rotated causing the cam followers to travel along the cam track so that the radial location of the cam track determining the radial position of the stripping pins.

Abstract: An envelope, bag or other mailing device for preventing the shifting of an item located within the envelope and a method for making the same is provided. The envelope includes a front panel, a back panel and at least one protrusion. The back panel is coupled to the front panel to form an interior portion formed between opposed interior surfaces of the front and back panels. The protrusion is coupled to one of the opposed interior surfaces and extends into the interior portion of the envelope. In another embodiment, a second protrusion is coupled to the other side of opposed interior surfaces and extends into the interior portion of the envelope. The protrusions are adapted tp associate with one another to protect items contained within the envelope from external forces and prevent the item from moving around within the interior portion of the envelope.

Abstract: A flexible die is provided which incorporates a base die and a superimposed interchangeable cutting or embossing die. The base die is generally planar and is adapted to securely receiving the superimposed interchangeable die thereon. Protruding upwardly from the outer face of the base die is a raised cutting portion, a raised embossing portion, or both, which raised portion is adapted to cut, form, or emboss the outer periphery of a blank or substrate. The superimposed interchangeable die is generally planar, and includes a raised cutting or embossing portion protruding upwardly from the outer face thereof, which raised portion is adapted to cut, form or emboss a portion of the blank or substrate. At least a portion of the superimposed interchangeable die is adapted to be received onto at least a portion of the base die.

Abstract: The invention relates to a rotating cutting device for producing letter envelope cuts from a printed endless, moving material web. The position of the cut is pre-set by register marks printed on the web. In this process, the cutting device is fully automatically synchronized with the register marks. This is accomplished via a computer-supported controller which, via sensors, first determines the spacing between two adjacent marks, then adjusts the cutting device to the determined length of the section, and finally continually monitors the phase position between the knife and the register mark and changes the phase position by slightly accelerating or slowing down the material web until the cut and the register mark coincide.
