Abstract:
A method of heating sheets of glass includes a step of arranging a plurality of sheets vertically in a juxtaposed manner inside a predetermined space defmed by an outer boundary. The method further includes a step of surrounding the predetermined space with heating elements such that the heating elements extend across substantially all of the outer boundary. The method further includes a step of moving the predetermined space with the plurality of sheets therein through a plurality of thermal zones. The method further includes a step of, for each thermal zone, maintaining a heating intensity of the heating elements to be substantially the same as one another within that the thermal zone. The method further includes a step of changing the intensity of the heating elements in at least one of the thermal zones. Moreover, there is provided an apparatus for heating sheets of glass comprising a furnace (14) an a plurality of vehicles (22) or accomodating each a plurality of glass sheets (12), each vehicle (22) comprising heating elements (62, 64). Furthermore an assembly with a frame and a clamp (52) for transporting a sheet of glass is provided.

본 발명은 박판 유리의 절단 모서리 가공 장치에 관한 것이다. 보다 상세하게는 유리판의 절단 모서리에 형성된 미세한 크랙을 제거하기 위한 장치에 관한 것이다. 본 발명에 따른 유리판의 절단 모서리 크랙 제거 장치는, 유리판의 절단모서리를 용융시키기 위한 버너와, 버너에 연소가스를 공급하기 위한 연소가스 공급수단과, 유리판을 파지하여 버너에 근접시키기 위한 로터리 진공흡착그리퍼를 포함한다. 버너는 화염방사면과, 화염방사면에 형성되고 이웃하는 화염방사홀를 연결한 가상의 선이 적어도 하나의 단일폐곡선이 되도록 배치된 복수의 화염방사홀을 포함한다. 로터리 진공흡착그리퍼는 버너의 화염방사면과 평행하게 배치된 회전축과, 일단이 상기 회전축에 고정되고 타단에 흡착면이 형성된 진공흡착아암을 포함한다.진공흡착아암은 회전축의 회전시 정해진 위치에서 흡착파지된 유리판의 일면을 버너의 화염방사면을 향하도록 설치되어 있다. 로터리 진공흡착그리퍼는 생산성 향상을 위하여 복수의 진공흡착아암을 구비하는 것이 보다 바람직하다. 또한 복수의 진공흡착아암의 흡착면은 각각 회전축의 일회전에 대하여 진공흡착구간에서는 진공이 걸리고 진공해제구간에서는 진공이 해제되도록 되어 있다.
Abstract:
In an embodiment of the invention, a tong assembly for handling glass articles such as bottles, jars, and the like during the manufacture of same, utilizes replaceable matched pairs of components that vertically seat and are captured on features on the pair of tongs. The components may be in an interlocking, gravity restrained engagement and that may be replaced by lifting the components out of their interlocking engagement, removing them and replacing same by lowering the replacement components into the interlocking engagement whereby the replacement components are then captured and constrained by pairs of engagement surfaces. Lowering may be by lowering the entirety of the insert or lowering a portion such as the component is rotated into seating engagement. The components may be inserts held in place with the resiliency of spring clips that are themselves retained on the inserts also by the spring clips resiliency. Matched pairs of components are movable toward and away from one another as the tongs are closed and opened for grasping and releasing the upper portions of glass articles such as bottles and jars. The matched pair of components may be inserts for engaging the upper portion of the glass articles, the inserts captured within interlocking portions of takeout jaws. The matched pair of components may be protective covers.
Abstract:
A fabric (30) is adapted for covering at least partially a ring for quenching glass which has been bent. The fabric (30) comprises at least three strips (32, 34, 36): a strip (32) of a high-density knitted structure for quenching the glass and two strips (34, 36) of a lower density structure for attaching the fabric (30) to the ring.
Abstract:
A sheet restrainer is used to restrain movement of continuously traveling glass sheet and includes arms on either side of the glass sheet. A driving device coupled to the arms moves the arms from a retracted position in which the arms are withdrawn from the glass sheet to an engaged position in which the arms are near the glass sheet and in alignment with each other. Rollers are connected to the arms and contact the glass sheet in the engaged position. A damping device applies an adjustable damping force to at least one of the arms dampening movement of the arm in the engaged position thereby restraining movement of the sheet. In a method of operation, the damping devices restrain angular and/or lateral movement of the sheet by transmitting movement of the sheet against the rollers into a resistive damping force of the damping devices.
Abstract:
L'invention concerne un procédé de préparation d'une feuille de verre bombée comprenant une ouverture, comprenant un bombage suivi d'un refroidissement, la périphérie de la feuille et la périphérie de l'ouverture étant soutenues au moins au début du refroidissement par un squelette.
Abstract:
A glass sheet guidance system includes a guidance member (22) having a small contact area with the glass sheet (12) and being taut to provide guidance to the glass sheet. In order to provide consistent guidance, even in environments where there is a large change in temperature, the guidance member is held taut by a tension member (24). The guidance member is supported by holders (10) so that, while remaining taut, the guidance member can be moved in three dimensions so as to accommodate glass sheets having different widths (1), heights (2), and thicknesses (3). Also, there is provided a method of guiding glass sheets with the guidance system.
Abstract:
Disclosed are devices and methods for supporting glass sheets during a thermal treatment process, such as heat treating, to maintain the physical geometry of the glass sheets. The device can comprise means for separating adjacent glass sheets to prevent them from touching. The separating means can comprise a separation comb having projections and channels configured for receiving the glass sheets, separating rods configured to be positioned between the glass sheets, or a combination of separation combs and separating rods.
