Examine and measure completed materials or products to verify conformance to specifications, using measuring devices such as tape measures, gauges, or calipers. Adjust machine components according to specifications such as widths, lengths, and thickness of materials and amounts of glue, cement, or adhesive required. Monitor machine operations to detect malfunctions; report or resolve problems. Read work orders and communicate with coworkers in order to determine machine and equipment settings and adjustments, and supply and product specifications. Fill machines with glue, cement, or adhesives. Mount or load material such as paper, plastic, wood, or rubber in feeding mechanisms of cementing or gluing machines. Maintain production records such as quantities, dimensions, and thicknesses of materials processed. Start machines, and turn valves or move controls to feed, admit, apply, or transfer materials and adhesives, and to adjust temperature, pressure, and time settings. Perform test production runs and make adjustments as necessary to ensure that completed products meet standards and specifications. Remove jammed materials from machines and readjust components as necessary to resume normal operations. Align and position materials being joined in order to ensure accurate application of adhesive or heat sealing. Observe gauges, meters, and control panels to obtain information about equipment temperatures and pressures, or the speed of feeders or conveyors. Remove and stack completed materials or products, and restock materials to be joined. Clean and maintain gluing and cementing machines, using solutions, lubricants, brushes, and scrapers.
