This document discusses a stenter machine used in textile manufacturing. It defines a stenter machine as a machine used for stretching fabrics after weaving. The key functions of a stenter machine are drying, heat setting, width and shrinkage controlling. It describes the working principle which involves passing fabric through padders and chambers with burners and filters to apply heat and stretch the fabric. Specifications of a Bruckner stenter machine are provided, including a speed range of 15-30 m/min and temperature range of 50-250°C.

WORKING PRINCIPLE OF STENTER MACHINE (CONT.)
• The circulating fans blow air from the base to the upper side and
exhaust fans sucks all the hot air within the chambers.
• Attraction rollers are provided to stretch the warp yarn.
• After stentering we can increase the width of the fabric up to 1.5-2 inch.
• The speed of the machine is about 7-150 m/min.
• Temperature is adjusted that according to the fabric.
