In a pultrusion device for producing continuous length sections prepared from thermoplastic resins reinforced with long fibers, the vertical angle (.alpha.) of an upstream conical surface of a conical portion, which constitutes a shaping nozzle perforated through the downstream end wall of the device ranges from 15 to 35 degrees and the shaping nozzle has a land portion having a length of 1 to 5 mm in the downstream area subsequent to the upstream conical surface. According to this pultrusion device for producing continuous length sections prepared from thermoplastic resins reinforced with long fibers, the long fibers never undergo any breakage nor fluffing during the opening treatment and this accordingly leads to the substantial reduction of pill-formation. As a result, the opening-impregnation device of the present invention provided at least with the downstream end wall carrying the shaping nozzle (including the land portion) can stably and continuously be operated over a long period of time, without any trouble such as those encountered in the conventional devices.

A high speed input system for an inserter machine. The system controlling a guillotine cutter, a cutter transport, and an upstream web handler transport to increase throughput for mail production. The controller is programmed to control the high speed input module in accordance with a repeating cycle. The cycle time is determined as an amount of time between a first web feed request and an earliest possible time that a subsequent second web feed request can be acted upon. A cutter transport motion control profile initiates feeding of a document length of web after receiving the first feed request. The cutter motion control profile causes the cutter blade to begin descending when the cutter transport has moved the web a trigger distance, calculated such that the cutter blade will first make contact with the web immediately when the web has been halted by the cutter transport motion profile. A web handler transport profile moves the web the document length at velocities and accelerations less than the velocities and accelerations of the cutter transport. At the end of the cycle, the web handler transport causes the web to be transported at a nominal velocity selected to maintain an appropriate amount of the web loop in the web handler. Within the web handler a control loop expands and contracts as the downstream cutter transport stops and starts as the cutter blade cuts the web in each cycle.

Toys and toy components are formed of a conductive loaded resin-based material. The conductive loaded resin-based material comprises micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The percentage by weight of the conductive powder(s), conductive fiber(s), or a combination thereof is between about 20% and 50% of the weight of the conductive loaded resin-based material. The micron conductive powders are metals or conductive non-metals or metal plated non-metals. The micron conductive fibers may be metal fiber or metal plated fiber. Further, the metal plated fiber may be formed by plating metal onto a metal fiber or by plating metal onto a non-metal fiber. Any platable fiber may be used as the core for a non-metal fiber. Superconductor metals may also be used as micron conductive fibers and/or as metal plating onto fibers in the present invention.

In the production of elongate plastic profiles (10), which usually takes place by the pultrusion process, the cured plastic profile (10) emerging from a die (14) is pulled through the stationary die (14) by a take-off device. This process only makes it possible to produce straight plastic profiles (10). The invention envisages producing curved plastic profiles (10) by using a die (14) corresponding to the curvature of the plastic profile (10). For moving the cured part of the plastic profile (10) out of the die (14), it is provided that the die (14) is moved back step by step in relation to the stationary plastic profile (10) counter to the direction of production (19). In order that the plastic profile (10) remains stationary in relation to the die (14) as this takes place, it is securely held outside the die (14) by a holding means (20) during the moving back of the die (14).
