A speed control assembly for a rotatable web winding apparatus comprising a dancer engaged with a web of material wound about the winder apparatus for displaceably responding within a predetermined range of dancer positions to tension variations in the web; a first control signal generating device for generating a first control signal in response to dancer displacement from a predetermined centered position, the ratio of dancer displacement to the first control signal being variable over the range of dancer displacement positions; and a dancer response rotation control device for rotationally accelerating the winding apparatus in response to the first control signal.

Winder speed control apparatus

A method and apparatus controlling the lateral position of a moving web of material having a central longitudinally extending web axis extending generally parallel to the direction of movement of the web so as to maintain the central longitudinally extending axis of the web at a substantial constant lateral position relative a fixed longitudinally extending axis associated with a fixed web alignment station based upon the detected longitudinal distance between certain portions of a series of longitudinally spaced apart, substantially identical, generally transversely extending indicia in a longitudinally extending indicia path parallel to the central longitudinal axis of the web.

Web lateral position control apparatus and method

An apparatus for monitoring the phasing relationship of a moving web of material of the type having a repeating series of graphics patterns thereon which repeat at ordinarily constant distance repeat length intervals of web travel and which contain separate repeating indicia portions which define a repeating indicia set which are positioned in a repeating indicia path extending longitudinally of the web comprising: an indicia detection device for providing an indicia detection pulse signal; a web travel sensing device for providing a web movement signal; an indicia profiling device for processing the indicia pulse signal and the web monitoring signal for generating a unique indicia image for each of the repeating indicia in a selected repeat length portion of the web; an indicia image storage device for identifying and storing the indicia images from a first selected repeat length portion of the web; a register indicia designation device for initially designating one of the repeating indicia to be register indicia; a register indicia sensing device for providing a register indicia pulse signal having pulses which in normal operation corresponds to the detection of the selected register indicia; a register indicia verification device for verifying that the repeating indicia which is in synchronization with said register indicia pulse signal is the currently designated register indicia; and a register indicia correction device for designating the indicia that is in synchronization with said register indicia pulse signal as the register indicia and replacing the previously designated register indicia therewith when the indicia image of the current register indicia is not verified to be the indicia which is in synchronization with the register indicia pulse signal.

Obstructed-field-indicia-sensing device

A method and apparatus for controlling the phasing of repeat length portions of a moving web to an operating machine along the web including method and apparatus for measuring instantaneous phasing error between web portions being operated on and the operating machine; method and apparatus for measuring repeat length error in web portions upstream of the operating station; method and apparatus for determining the total distance by which a web portion is out of phase with the operating machine before the web portion is operated on by the operating machine, method and apparatus for adjusting the movement of a web portion relative the movement of the operating machine during the last repeat length of web travel of the web portion before it is operated on by the operating machine; and method and apparatus for monitoring and correcting the phasing adjustment response.

Phasing control system for web having variable repeat length portions

A method of generating a signal indicative of the passage of indicia on a moving web of material at a preselected reference station along the web without use of an indicia sensing device at the selected reference station comprising locating an indicia sensing device at a sensing station at a preselected distance of web travel upstream of the reference station; generating an indicia detection signal having sensing pulses coinciding with the passage of indicia at the sensing station; measuring the distance of web travel occurring after each sensing pulse in the indicia detection signal; generating an indicia reference signal having reference pulses coinciding with the passage of indicia at the selected reference station by providing a reference pulse corresponding to each sensing pulse and occurring thereafter at a point in time at which the measured distance of web travel after a corresponding sensing pulse is equal to the preselected distance of web travel between the sensing station and the preselected reference station.

Web indicia reference signal generating system

A reheating and blow molding system utilizing an indexing plate having pairs of core pins mounted on the periphery. Radiant heaters heat parisons mounted on the core pin to a temperature suitable for blow molding while the parisons are rotated in response to movement of a spin belt. Rotation of the parisons during heating provides greater uniformity of heating. Tapered shanks remove the core pins from core pin holders and dispose the parisons in a mold for blow molding. The core pins are then disposed in the core pin holders and indexed to a subsequent indexing location where the finished article is removed.
