glue provide optimum control of consistency, the supplier claims. According to the company, its new unit also eliminates the need for open glue pans, separate cookers, manual handling of prepared glue, down time and manual stirring. Food Machinery & Chemical Corp., Packaging Machinery Div., 4900 Summer dale Ave., Philadelphia 24.

High-speed, variable-rate feeder

Syntron's Model F-010 electromagnetic vibratory feeder reportedly offers fast, high-capacity, rate-controlled feeding of bulk materials in weighing, blending, mixing, packaging and other processing operations. Its driving mechanism    produces

3,600 vibrations per minute to assure free flow of hard - to - handle bulk materials, the    supplier

claims. A rheostat control permits adjustment of the feed rate from a slow dribble to a maximum rated capacity of three tons per hour. The unit's standard flat-pan trough measures 5 in. wide and 24 in. long. Other shapes and sizes are available on order. Maintenance-free operation is afforded by a dust-tight enclosure for the electromagnet drive and by the absence of mechanical parts, says the company. Syntron Co., Homer City, Pa.

Metallic coating for aerosol cans

Crown Cork & Seal announces that it has developed a method for applying on aerosol cans a metal coating such as those used on large-surface products like automobiles, office furniture and communications equipment. First application is for a hair spray marketed in South Africa. The finish reportedly is uniform on sides, top and bottom; provides a metallic luster; is fadeproof, and is resistant to moisture and abrasion. The metallic coatings can be produced in a variety of colors and intensities. Crown Cork & Seal Co., Inc., Can Div., 9300 Ashton Rd., Philadelphia 36.

New bottle-inspection machine

Mayer Production Engineers has introduced its new Model B-2 bottle-inspection machine. Among the cited improvements in the device are: an automatic bottle gate that allows only rejected bottles to be discharged from the conveyor; electronic indexing that affords rapid and accurate adjustment for bottle changes and positive maintenance of adjustment; time-delay ejection control for greater accuracy in timing the rejection arm, and an accumulating table and guides for smoother discharge of rejected bottles and reduced breakage. Mayer Production Engineers, Inc., Lincoln Park, N.J.

Continuous printing on polyethylene film

A new flexographic printing press that reportedly prints polyethylene film in two or more colors without the need for stopping or reducing speed when joining rolls is available from Beasley, French & Co. The English-made Befanco press also is claimed to print at speeds of 450 ft. per minute. It is equipped with unit driers, a rotating mirror and web-scanning device, static eliminator, tension control and automatic pasters on both unwind and rewind ends. To permit rapid drying of the ink (as well as rapid cooling to prevent melting or distortion of the film), the unit driers blow heated air onto the web, quickly exhausting it through the unit so that heating is limited to about 6 in. of web travel, the supplier says. For continuous, high-speed press operation, each reel

stand carries two independently driven rolls of film. As one roll of film nears its end, an automatic operation causes the second roll (prepared and pasted) to rotate about its spindle until it attains the same speed as the web. At this point, a light appears on the control panel, the web is brought down onto the pasted roll, a joint is made and the empty reel is cut free by a swinging knife. A similar operation is performed at the rewind end. Beasley, French & Co., 110 E. 31 St., New York 16.

New line of aerosol crimpers

Five new aerosol-crimping machines have been introduced by John R. Nalbach Engineering. The company's Model 1-HC is a semi-automatic unit for crimping cap and valve assemblies in l-in.-diameter openings in aerosol cans. Requiring line pressure of 90 to 100 lbs. per sq. in., it operates at a rated speed of 20 to 35 containers per minute. Also available are four automatic crimper-”Models 4 H.C., 8 H.C. (non-vacuum heads on both), 4 H.V.C. and 8 H.V.C. (vacuum heads)  which operate at rated speeds of up to 300 containers per minute. Among the reported advantages of these machines are complete accuracy, rapid change-over, long service life and low maintenance cost. John R. Nalbach Engineering Co., 6139 W. Ogden Ave., Chicago 50.

Vacuum-pressure powder filler

A powder-filling machine designed for use in laboratories and in limited-production packaging operations is offered by Perry Industries. The Perry Accofil Lab Gun, as it is called, employs a vacuum-pressure principle patented by Lederle Labora

tories. It consists basically of a cylinder and adjustable piston combination into which a vacuum-pressure cycle is introduced. In operation, the piston is adjusted to the exact fill required (up to several pounds). Then the cylinder is inserted into a bulk powder container, where it picks up a pre-selected amount of powder. The operator inserts the cylinder into the container to be filled, then presses a foot pedal to deposit the slug into the container. According to the company, the unit is accurate within 1% of pre-set weight. The unit is suggested for use in packaging a wide range of powdered products, including pharmaceuticals, cosmetics, foods, insecticides, seeds, photographic powder and aerosol-dispensed items. Perry Industries, Inc., 6401 Third Ave., Brooklyn 20.

One-piece, rigid polyethylene drum

A rigid polyethylene drum for storage and shipment of chemicals and similar dry or liquid products is offered by Plastineers. Marketed under the name Polyflexon, the one-piece, seamless drum has ¾6-in. walls and a capacity of 38 gallons. Measuring 18 by 35 in., the drum is produced on an injection-molding machine. According to the supplier, the lightweight drum compares in cost with steel drums and is resistant to many corrosive acids or chemical solutions. Plastineers, Inc., 605 IF. Broadway, Minneapolis.

Printing unit for shipping containers

Available from M-H Standard is the Morrison Printer Model T-29, a conveyorized printing machine that is reported to be suited for printing corrugated shipping cartons or other flat,
