Abstract
A process and apparatus for handling a rigid sheet is disclosed. The process comprises engaging opposing faces of a sheet at its periphery with engagement means providing a second engagement means, movable relative to the first and engaging the sheet with the second engagement means. The sheet is then moved relative to the second engagement means whilst the sheet is engaged with the first engagement means and is then clamped. The sheet is then moved to a desired orientation or location whilst maintaining the first and second engagement means in fixed relative position. The process is useful in handling glass sheeting and in the production of multiple glazed units and on an insulating glass production line.
Claims12
A multiple-sheet product comprising a first rigid sheet and a further rigid sheet in a parallel relationship wherein the edges of the first rigid sheet and the further rigid sheet are sealed to enclose a volume between the said sheets, the multiple-sheet product being produced by a process in which the first rigid sheet is moved from a first location to a second location by a process comprising:
- i) providing first engagement means configured to engage the first rigid sheet on a peripheral area of the said sheet and providing second engagement means, the first and second engagement means being adapted so as to enable relative longitudinal movement between the first and second engagement means configured to carry the weight of the first rigid sheet;
- ii) locating the first engagement means adjacent to the first rigid sheet and engaging the first rigid sheet on the said peripheral area;
- iii) locating the second engagement means adjacent to the first rigid sheet;
- iv) optionally effecting relative longitudinal movement between the first rigid sheet and the second engagement means whilst the first rigid sheet is engaged by the first engagement means;
- v) engaging the first rigid sheet with the second engagement means so the said sheet is held and its weight borne by the first and second engagement means;
- vi) retaining the first and second engagement means engaged with the said sheet in fixed relation and moving the said first and second engagement means and sheet to the said second location;
- vii) aligning the first rigid sheet with the further rigid sheet in a parallel relationship;
- and
- viii) sealing the edges of the first rigid sheet and the said further rigid sheet to enclose a volume between the sheets to provide a multi-sheet product.
A process for the production of a multiple-sheet product comprising two or more parallel sheets comprising:
- i) providing a first rigid sheet in a remote first location and a second rigid sheet in a second location;
- ii) moving the said first rigid sheet to the said second location;
- iii) aligning the first rigid sheet with the second rigid sheet in a parallel relationship;
- and
- iv) sealing edges of the first rigid sheet and the said further rigid sheet to enclose a volume between the sheets to provide a multi-sheet product;
- wherein the first rigid sheet is moved to the second location by:
- providing a first engagement means configured to engage the first rigid sheet on a peripheral area of the said first rigid sheet and providing a second engagement means, the first and second engagement means being adapted so as to enable relative longitudinal movement between the first and second engagement means and being configured to carry the weight of the first rigid sheet;
- locating the first engagement means adjacent to the first rigid sheet and engaging the first rigid sheet on the said peripheral area;
- locating the second engagement means adjacent to the first rigid sheet;
- optionally effecting relative longitudinal movement between the first rigid sheet and the second engagement means whilst the first rigid sheet is engaged by the first engagement means;
- engaging the first rigid sheet with the second engagement means so the said sheet is held and its weight borne by the first and second engagement means;
- and
- retaining the first and second engagement means engaged with the said sheet in fixed relation and moving the said first and second engagement means and sheet to the said second location.
