摘要:
A method of making a pair of rotary die cylinders with lands having coacting cutting edges which cut blanks from a web of material passing through the nip of the rotating dies. In cross section each land has an outer face and a pair of spaced apart side faces which are parallel to each other and perpendicular to the chord of the outer face to provide a clean cut and facilitate release of the cut blank from the cutting blades as it emerges from the nip of the dies. The die cylinders are journalled for rotation by recesses with frusto conical locating surfaces in their opposed ends. Each die cylinder is made by machining the recesses in the opposed ends of a generally cylindrical workpiece of tool steel and then utilizing the recesses to locate and orient the workpiece relative to a cutting tool to produce a cylindrical surface on the workpiece concentric with the axis of the recesses and then to machine away portions of the periphery of the cylindrical surface to form the cutting blade lands thereon. After machining is completed the cutting blade lands may be hardened by heat treating utilizing a laser beam directed onto the lands to heat them at an elevated temperature so that upon quenching they are hardened without any substantial hardening and resulting distortion of the core or body of the workpiece.

Method and apparatus for repetitively making products, such as cap liners continuously from web material. A rotary knife drum having an array of die cutters cooperates with a counter-rotating anvil to thereby define a convergent web working zone therebetween. A pair of servo-motor driven nip feeders feed a web through the convergent work zone of the drum and anvil. Motor and belt drive means continuously unidirectionally rotates the knife drum and anvil at a constant angular velocity, while the web feeder cycles to first advance the web through the work zone such that travel speed and direction matches that of each die cutter as it passes through the work zone in the web travel path to thereby cut a cap liner from the web, quickly stops and then retracts the web a given pullback distance when each die cutter travels clear of the web travel path and before the next cutter enters the same, and then resumes quickly web advance to match travel of the next die cutter as it passes through the web travel path to thereby cut another cap liner. The pullback mode thereby forms a condensed rollout web working pattern of liner cut-outs in the web. An array of transfer posts on a transfer roll travel into and out of individual registry and sequentially with the die cutters to thereby pick off cut liners from the cutters for transport travel on the posts. An escapement supplies caps side-by-side and shifts them into alignment with successive transfer posts for transfer of cut liners successively into the caps.

An improved headwear shaping device which is compact, lightweight, modular and contains an arcuate channel for receiving the visor portion of athletic headwear, shaping the visor by applying equal pressure throughout the perimeter of the visor. The shaping device also provides a stabilizing arm perpendicular to the inserted visor causing the visor to extend parallel to the horizontally axis of the cap for display and storage. The unitary shaped body of the invention is comprised of a lightweight, compact, cost-effective rigid material which also provides for enhanced portability of headwear while not in use.

The invention is utilized in the context of a peripheral device that is coupled to a network via a firewall which blocks unwanted incoming message traffic, except for incoming message traffic that is responding to a message dispatched from the peripheral device. A remotely located diagnostic device, which includes code for diagnosis of causes of peripheral device malfunctions, is connected to communicate via the network. The peripheral device includes a memory for storing a diagnostic application that is adapted to execute one or more diagnostic subroutines for diagnosing a cause of a device malfunction. The peripheral device is enabled to dispatch an event message to the remote diagnostic device and to receive a response message from the remote diagnostic device (all via the firewall and the network). The response message causes a diagnostic application to execute a subroutine on the peripheral device in an attempt to determine the cause of the event. In the case where the remote diagnostic device is adapted to download an executable diagnostic subroutine, the peripheral device executes the diagnostic subroutine.

An overcap assembly for a liquid container that prevents dirt from contaminating the container's integral top lid and sufficiently reseals the container's product-dispensing orifice after initial opening by means of a resiliently deformable sealing member which allows subsequent shaking of the container to redistribute suspended solids such as orange juice pulp. The overcap assembly may be hingedly fixed to or fully removable from the container.

Systems and methods are described herein for remote management of printing devices of various types within an enterprise. Printers that are not as well-equipped for printing device management (e.g. legacy printing devices and low-end printing devices) are taken into account by assigning printing device management elements and functions that are present in more modern higher-end printing devices to one or more host computers. As a result, printing device management tasks can be similarly applied to all types of enterprise printing devices without having to use multiple user interfaces or user processes.

A die apparatus for supporting and retaining rotary dies in operation having a base, a cover supported by a plurality of columns, a cross member moveable along the columns and modular die supports rollingly engaged with the rotary dies. A method of installing and removing the rotary dies from the apparatus includes moving the dies along a first axis of movement within the apparatus through use of a support strap and moving the dies to and from the apparatus through use of a conveyor.
