A glass manufacturing apparatus includes a delivery apparatus defining a travel path extending in a travel direction. The delivery apparatus conveys a glass ribbon along the travel path in the travel direction of the delivery apparatus. The glass manufacturing apparatus includes a first forming roll and a second forming roll spaced apart from the first forming roll to define a gap. The first forming roll and the second forming roll receive the glass ribbon along the travel path within the gap. A drive apparatus is coupled to the first forming roll and the second forming roll. The drive apparatus moves one or more of the first forming roll independently of the second forming roll or the second forming roll independently of the first forming roll to change a width of the gap.

Methods and apparatus for manufacturing a glass ribbon

An apparatus for drawing a glass ribbon including an edge roll assembly that contacts the glass ribbon with a force that is dynamically altered by an actuator electrically coupled to a sensor that measures the force applied against the ribbon. Dynamic, or real-time, variation of the edge roll force minimizes stress variability in the glass ribbon and improves ribbon shape control.

A print press system and a method are described herein that print an electronic circuit onto a material (e.g., glass substrate, plastic film, plastic film-glass substrate laminate). In exemplary applications, the print press system can print an electronic circuit onto a material to form, for instance, a flexible Liquid Crystal Display, a retail point of purchase sign and an e-book.

Roll mechanics for enabling printed electronics

Roller pairs and draw apparatus for processing glass ribbons are disclosed. The roller pairs applying force to a glass ribbon moving through the draw apparatus. The roller pairs include a first roller assembly and a second roller assembly positioned along opposite sides of the glass ribbon. A shaft of the second roller assembly is coupled to an actuation system that includes a repositionable support member allowing translation of the shaft of the second roller assembly in a direction transverse to the draw direction of the glass ribbon, a pneumatic actuator controlling a position of the contact wheel of the second roller assembly in the direction transverse to the draw direction of the glass ribbon, and a pneumatic reservoir in fluid communication with the pneumatic actuator delivering fluid at an elevated pressure to the pneumatic actuator.

Active edge roll control in a glass drawings process

An apparatus for drawing a glass ribbon including a shroud surrounding the glass ribbon and an edge roll that penetrates the shroud to contact the glass ribbon. The apparatus includes regulating a pressure within the seal assembly to be equal to or less than a pressure within the shroud and prevent ingress of relatively cooler outside gas into the hot interior of the shroud. The edge roll utilizes an air bearing to minimize friction that can produce periodic fluctuation of the ribbon as the edge roll is displaces in response to variations in the ribbon thickness or equipment dimensions.

Low friction edge roll to minimize force cycling

Methods and apparatus () for monitoring the tension () and pinch force () associated with the contact of angled stub rollers () with a glass ribbon () are provided. The apparatus () includes a support member () which supports the shaft () of the stub roller (). The support member () undergoes linear displacement () in response to tension () in the glass ribbon () and rotation () in response to a pinch force (). The linear displacement () and rotation () are detected and converted to force values by a calibration procedure. By monitoring these forces, glass attributes such as residual stress can be improved which is of importance in glass sheets used in such applications as the manufacture of liquid crystal displays.

Force monitoring methods and apparatus

A machine tool having a quick release draw tube includes a headstock with a spindle. A draw tube is slidably supported within the spindle and includes inner and outer surfaces. The draw tube includes a series of circumferentially spaced holes on the outer surface thereof. A draw tube locking or unlocking device cooperates with the spindle and includes a ball detent that is selectively received in one of the recesses provided on the draw tube for locking the same within the spindle. The machine tool also includes an adapter plate for mounting over the extended nose of the spindle for substituting a collet by a jaw chuck.

A machine tool comprises a base, a spindle operably associated with the base, a work holder operably associated with the spindle for securing a workpiece to the spindle, and a tailstock operably secured to the base. The tailstock includes a slideway and a tailstock body slidably secured to the slideway. The tailstock body is movable on the slideway between a home position away from the workpiece and a work engaging position. A limit switch and trip members associated with the tailstock, and a hydrulic circuit are provided for controlling the movement of the tailstock body from the home position to an intermediate position prior to the work engaging position at an initial feed rate and from the intermediate position to the work engaging position at a subsequent feed rate where the initial feed rate is greater than the subsequent feed rate.

A headstock cooling system for a machine tool comprising a base having a top, bottom and a first fluid passageway extending centrally therethrough from the top to the bottom. A bed is mounted on the base top and provided with a second fluid passageway extending coaxially from the first fluid passageway and in fluid communication therewith. A headstock is mounted on the bed and is positioned coaxial with and directly above the second fluid passageway and includes means for communication with the second fluid passageway for directing a cooling fluid from the second fluid passageway out of the headstock thereby cooling the headstock over at least a substantial portion of the headstock.
