West Show a success

About 7,300 industry personnel attended the seventh biennial Western Packaging & Materials Handling Exposition, held Aug. 11-13 at San Francisco's Civic Auditorium. This attendance figure, plus the number of exhibitor-�139 ranked the 1958 show as one of the most successful in the series. Two years ago at Los Angeles, the show drew a record attendance figure of 8,600 to its 148 exhibits.

A feature of this year's exposition was a one-day packaging and materials-handling clinic, conducted by consultant William H. Jahnicke and sponsored by the Western Packaging Assn.

The Western show will return to Los Angeles in August, 1960, according to Clapp & Poliak, managers and sponsors of the event.

on weighing efficiency in your plant!

For proper cost control, efficient weighing is a prime requirement. Weight records directly affect costs, quality, inventory control and customer billing. You can avoid weighing errors and inadequate weight data by placing the right scales in the right places ... all properly integrated in a plant-wide weighing system to supply basic accounting records on materials received, transferred and shipped.

You can easily check up on the job your scales are now doing. Just ask for the exclusive Toledo Weight Fact Kit. A Toledoman will gladly explain how it will help you detect and correct weighing inefficiencies in your plant.
