Four Middle Tennessee manufacturing operations are eliminating more than 300 jobs, according to the state's weekly layoff report.

The Tennessee Department of Labor & Workforce Development has received notices from four companies combining on 333 layoffs, dating back to September.

The largest of the four came from Albany International Corp., which will be eliminating 156 jobs from its Portland fabric manufacturing plant, the closing of which was announced in July. According to the company, the layoffs began in September and the plant will shut down completely early next summer.

Creve Coeur, Mo.-based Smurfit-Stone Container cut 37 jobs from its Murfreesboro location in September. The company, a paper and packaging giant which employs 21,000 people worldwide, filed for Chapter 11 bankruptcy protection in January.

The company filed its reorganization plan earlier this month, hoping to emerge from bankruptcy next summer. The Murfreesboro facility avoided the fate of two other company plants in Montana and Ontario, which will be closed as part of the effort to get out of the red.

Also in Murfreesboro, L&W Engineering, an aluminum and steel fabricator primarily serving the automotive and manufactured-home industries, eliminated 85 jobs in late November. The plant, the first tenant in the Elam Farms industrial park in Murfreesboro, opened in 2008.

In Cheatham County, Trinity Marine Corp. laid off 55 workers in cutbacks that began in October. The Dallas-based corporation bought the former Nashville Bridge Co. in 1995 and relocated to Ashland City after the construction of LP Field forced the demolition of its East Bank headquarters.

Across Tennessee, manufacturers cut almost 30,000 jobs in the year ended Nov. 30.
