Title: Ray E Welcher: Innovator in Automatic Sewing Technology
Introduction
Ray E Welcher is a notable inventor based in Danvers, MA (US). He has made significant contributions to the field of automatic sewing technology, holding a total of 2 patents. His innovative designs have advanced the capabilities of sewing machines, making them more efficient and versatile.
Latest Patents
Welcher's latest patents include an "Automatic Stitching Apparatus" and a "Method and Apparatus for Controlling an Automatic Bar Tacking Machine." The Automatic Stitching Apparatus features clamps that hold the workpiece and define multiple sewing patterns. A digital control system within the sewing machine indicates the specific pattern to be executed. This system automates the stitching process by reading a set of stored instructions, which can be adapted for different patterns. The process concludes with the automatic ejection of the clamped workpiece.
The second patent, the Method and Apparatus for Controlling an Automatic Bar Tacking Machine, involves a sewing machine where the workpiece is moved under the sewing head by a clamp driven by stepping motors. These motors operate along two coordinate axes, following a predetermined pattern. The control of the stepping motors is managed by a coded Programmable Read Only Memory (PROM), which generates signals in sync with the sewing machine's operations. This innovation allows for precise stitching while compensating for the non-linearity of the linkage system.
