US Patent 3,463,692, granted 26 August 1969 to Frederick T. Brunner and assigned to Brunner Bros. Co., describes Schiffli embroidery worked with a thermoplastic bobbin (back) thread and a conventional front thread. Applying heat and pressure, for example with an electronic heat sealer, fuses the back thread to a support fabric. This attaches the embroidery without sewing and without stiffening the garment. The document has a drawing sheet (Figs. 1-9), the specification, six claims, and a list of references cited.
