Equipment and materials

in. wide and 5 to 30 in. long. A patented baffle system which controls the air flow automatically opens and loads up to 1,200 bags per hour, according to the supplier. The steel used in the machine is nonmagnetic, to facilitate opening of polyethylene bags, which are prone to static blocking. Other cited features include product guides for easier loading, adjustable air generator and a specially contoured feeder tray. Errich International Corp., 5 E. 35 St., New York 16.

Air-blower static eliminator

Simco has developed a new machine consisting of a series of ionizing air nozzles mounted on a metal frame that is claimed to offer a positive method for separating and neutralizing sheets of paper (coated or uncoated) or plastic which

are fed from stacks. Each of the nozzles is fitted with static eliminators energized by a small power unit. Air is supplied to the nozzles at pressure ranging from 15 to 50 p.s.i. (adjustable by opening or closing a master stopcock mounted adjacent to the series of nozzles). The air-nozzle assembly is located behind and slightly above the feed pile. Ionized air from the nozzles flutters the top few sheets, neutralizing static charges as the sheets are separated and eliminating any tendency for more than one sheet to be picked up at a time, the company says. The Simco Co., Lonsdale, Pa.

Spout assembly assures smooth product flow

American Flange & Mfg. has added a new item to its "Tri-Sure" line of spout assemblies designed for use by packagers of liquid products in metal pails. It is a self-venting, clinch-on, pull-up spout that reportedly assures smooth, even flow of light or viscous products. The new l¾-in. spout assembly permits controlled product flow of the pail's contents from beginning to end, the supplier says. American Flange & Mfg. Co., 30 Rockefeller Plaza, New York 20.

Giant six-color flexographic press

What is claimed to be the largest single-impression flexographic press ever built for printing on packaging films has been delivered to Regency Plastics Co., Woodside, N. Y., by Hudson-Sharp. The six-color press prints web widths up to 75 in., with print repeats up to 63 in. The unit, which has 8-in. inking rolls rather than the company's standard 5- and 6-in. rolls, is claimed to offer hairline register between colors and in print repeats. Other cited features include: hydraulic plate-cylinder throw-outs; continuously operating, splashproof ink fountains; running register peripheral and longitudinal plate-cylinder adjustments; close infeed and out-feed web tension at all running speeds; constant-register print repeats from roll to roll, and a heavy-duty, flying-splice unwind and rewind that permits non-stop operation of the press. Hudson-Sharp Machine Co., Sub. Food Machinery & Chemical Corp., Green Bay, W is,

Double-laminated foil carton

Designed for improved insulating qualities, Excel-O-Therm's new ice-cream container is fabricated of kraft board laminated on both sides with aluminum foil. According to the company, its new carton insures more rapid hardening of the product, offers better protection during storage and practically eliminates product loss through dehydration. Other cited advantages of the re-usable container include: absence of paper taste, better keeping qualities from store to home and elimination of warm ice cream around the edges of the carton. Excel-0-Therm Container Corp., Lexington, Ky.

Machines for orienting polyvinyl chloride

Machines designed for lateral and longitudinal orienting of polyvinyl chloride and similar packaging films are being made available by Inta-Roto. The film is first stretched in the lengthwise direction (at an approximate ratio of 1:3) on the longitudinal machine; then in the crosswise direction (at an approximate ratio of 1:2) on the lateral machine. According to the supplier, temperature controls on both units permit the correction of films of uneven caliber. The Inta-Roto Machine Co., Richmond 3, Va.

Imprinter for continuous-feed wrappers

Gottscho's Model P-11 "Wrap-A-Printa" is a new attachment designed for roll-leaf imprinting on continuous-feed wrapping and bag-making machines. The company's previous model was intended for use on intermittent-feed machines. The new unit operates like an automatic typewriter to make impressions of code dates or other legends through a ribbon of leaf material. According to the supplier, the attachment makes crisp, rub-proof impressions and also eliminates ink-drying problems on such hard-to-print stocks as polyethylene, cellophane, aluminum foil and waxed paper. Gottscho claims that 1,000 codedate impressions can be obtained with 5 cents worth of leaf, available in various colors. Adolph Gottscho, Inc., Hillside, N.J-

"Pul!-push' closure for squeeze bottle

Elimination of the harassment of lost or misplaced caps is one of the advantages claimed by U. S. Cap & Closure for its permanent, two-piece "pull-push" polyethylene closure for squeeze bottles containing liquid products.

The closure consists of an outer and an inner section. To use, the outer, reversed - taper flare cap is pulled up, effecting an opening through which the contents of the bottle can be is pushed down against the shoulder of the bottle, an effective seal is achieved, according to the supplier. U. S. Cap & Closure, Inc., 77 W. Washington St., Chicago 2.

Electronic batching scale aids accuracy

A constant-feed batching scale claimed to be accurate within 0.1% for wet or dry materials fed at rates of 5 lbs. to 5 tons per hour has been introduced by Thayer. According to the supplier, this accuracy stems from the use of an electronic closed-circuit control. Since the control has no mechanical parts to wear down during usage, high accuracy and constant speed control can be maintained over long periods, the supplier claims. Thayer Scale & Engineering Corp., Pembroke, Mass.

Micrometer lor thin-gauge materials

A new micrometer caliper, developed for checking or comparing the thicknesses of packaging materials where exact readings are necessary, has been introduced by E, J. Cady. Called
