Abstract
A shaped cord (2) is postformed in the shape of a frame extruded onto a glass (1) and is slightly curved in the direction of the length of shaped cord (2). A forming mold (4) is used in a postforming operation, with lateral edges (11, 12) that are slightly above the surface of shaped cord (2). This avoids the creation of imprints in the form of lines or edges on the shaped cord, and a smooth transition is achieved between the postformed length of the shaped cord that attaches thereto.
Claims18
A method for postforming a length of polymer shaped cord that has been extruded onto an object and which rises a predetermined height above said object, which comprises applying on the cord a forming surface extending in a direction along the length of the cord, said forming surface having:
- (a) a first section extending along said direction for, at least in part, engaging said object;
- (b) a second section extending along said direction and disposed laterally of said first section for overlying said cord when said first section is in engagement with said object;
- and
- (c) said second section having first and second portions extending along said direction, said first portion being disposed at a first height above said object which is less than said predetermined height and said second portion being disposed at a second height greater than said predetermined height, said first and second heights being measured when said first section is in engagement with said object, thus postforming said cord.
A method for postforming a length of shaped polymer cord having a predetermined height on an object, which comprises applying on the cord a forming surface extending in a direction along the length of the cord, said forming surface having:
- (a) a first section extending along said direction for, at least in part, engaging said object;
- (b) a second section extending along said direction and disposed laterally of said first section for overlying said cord when said first section is in engagement with said object;
- and
- (c) said second section having a center and two end portions extending along said direction, said center portion being disposed at a first height less than said predetermined height and said end portions being disposed at a second height greater than said predetermined height, said first and second heights being measured when said first section is in engagement with said object, thus postforming said cord.
A method for postforming a length of shaped thermoplastic polymer cord, which comprises applying a shaped thermoplastic polymer cord having a predetermined height on an object;
- and applying on the cord a forming surface which has portions of different heights, one of which is less than the said predetermined height and the other of which is greater than the said predetermined height, in order to postform said different heights onto the length of shaped polymer cord.
