Abstract:
Push roll spools for engaging and driving softened glass tubes over a shaping mandrel. A push roll spool for use in processing a glass tube may comprise a base having first and second axially spaced ends, and multiple sheets of heat resistant material disposed on the base between the axially spaced ends, forming an axially extending stack. The stack may have a circumferential, generally U-section groove having a profile defined by the peripheral edges of multiple said sheets having different diameters. The U-section groove may be sized to engage and drive a glass tube. The U-section groove may have two contact areas at which to engage and drive a glass tube. The heat resistant material may comprise mica or a mica composition, for example mica paper or ceramic fiber millboard.
Abstract:
A cartridge assembly includes a hub portion having a first end and a second end, a first retaining ring portion including a first snap ring and a first retaining ring member, and a second retaining ring portion including a second snap ring and a second retaining ring member. The cartridge assembly further includes a plurality of disc elements positioned between the first retaining ring portion and the second retaining ring portion, where the plurality of disc elements has an outer diameter that is greater than an outer diameter of the first retaining ring portion and the second retaining ring portion, and a plurality of fastening members positioned at the first end and the second end of the hub portion, the plurality of fastening members extending radially inward from the hub portion.
Abstract:
A method of field shaping a laminated glass structure is provided. The method includes providing the laminated glass structure comprising a flexible glass sheet having a thickness of no greater than about 0.3 mm laminated to a non-glass substrate by an adhesive material. The laminated glass structure is field cut using a handheld power tool thereby forming a shaped laminated glass structure. An edge strength of a cut edge of the shaped laminated glass structure at least about 20 MPa.
