An article by C. Martini, a finishing-plant operator, on foreign objects such as wire, nails, pins, heddle and harness parts, and reed fragments that get woven into gray cotton goods and later damage cloth and finishing machinery. He describes how calender rolls stencil damage into cloth, why mill inspection often misses these objects, and how weaving mills mark defects with pins or hooks. Twenty-four photographic figures illustrate examples, and he urges closer cooperation between weaving mills and finishers.
