Mixed with water to make an excellent lubricating solution for the shear blades cutting molten glass gobs on bottle manufacturing machines.

SHEAR SPRAY LUBRICANTS

Molyduval Gloria shear spray lubricants are designed to provide extended shear blade life, excellent shear cut, corrosion protection, reduced shear marks and cost-effective performance. These features translate into easy maintenance of the shear spray system.  
Different operating and water quality parameters primarily dictate what type of product will offer optimal lubrication. Molyduval Gloria has developed several types of shear oils – each with the same objective to provide optimal lubrication while reducing maintenance.

  • Soluble oil for recirculating/recycling dosing systems
  • Lubricant for use with precise dosing systems (graphoidal)
  • Excellent emulsion and hard water stability.

GOB shear lubricants

Molten glass is discharged from a feeding device in the form of a flowing stream. Gob cutting shears are mounted adjacent the feeding device and are reciprocated to sever the end portion of the glass stream causing it to fall free as a glass gob or mold charge. The prior art shear blades are of a "V" configuration, have a generally curved cutting surface and are in surface-to-surface contact. The shears are moved in a reciprocal motion by a pair of mounting arms which in turn are controlled and moved by a cam and follower mechanism or other mechanisms. The present design of the shear blade apparatus became known about the year 1918 and has continued virtually unchanged to the present day. It has been the practice in the past to lubricate the shear blades by spraying the blades between cutting cycles with an oil-water emulsion. The oil serves to lubricate the blades as they slide over each other and the water keeps the blades cool. In some prior instances, the spraying of shear blades was with an oil-water mixture and the mixture would eventually end up in the drain where a separation would be effected to prevent oil entering the municipal waste systems. When water-oil emulsions were formulated and used, it became necessary to find ways to break the emulsion in order to clean up the effluents in the plant waste system. When water spray, without other additives, was used, it was necessary that stainless steel be used; otherwise the blades would become rusty and iron oxide would flake off the blades.

The cutting device known as "shears" is positioned beneath the glass feeder. The shearing device is actuated by a driving mechanism which is controlled by a cam mechanism. The shape of the cam determines the number of cuts in a given period of time and also the operating speed of the moving shear blades. A typical pair of shear blades move in parallel planes which are usually horizontal and normal to the center line of a feeder discharge orifice. In the process of shearing glass, a volatile fluid such as oil is applied periodically to the blades to lubricate them and water is sprayed on them to cool them. The improved shear blades of this invention represent a departure from shear blade design which has remained static since about 1918. Normally functioning prior art shear blades depended on the correct adjustment of tension between the blades in order to have good shear life. It is an art to adjust blade tension which gives a gob sheared smoothly and yet without excessive wear to the shearing blades.
