Wide Screen Frames

A Look at Some of the Problems Involved in the Use of Curved and Straight Screen Frames With Various Wide Screen Systems

BRIEF: With the development and acceptance of the various wide screen forms of screen presentation . . . a number of problems have naturally arisen as a result . . . One of the areas which has been under a great deal of change . . . naturally . . . has been the size and shape of the screen frame . . . and the stage . . . The need to have wide screen frames . . . some curved . . . created quite a problem as regards flying . . . so as to be able to use the stage for live presentations . . . This article . . . prepared by a veteran expert in the field of stage and screen frame construction . . . offers some sage advice on this subject . . . with particular emphasis on how the problem of flying the structure may be solred . . . There is other information . . . of a more general nature . . . covering other sectors of this particular problem . . . which is currently the cause of much concern to many large and small exhibitors . . . Some of the answers will he found here.

* In the past year there have been major and outstanding changes from the standard motion picture presentation to the new CinemaScope method of presenting motion pictures. The ultimate desired result is to give the public a larger, clearer, panoramic type of pres

entation. This necessitated the development of stereophonic sound which helped to obtain this desired effect.

In addition to the new type lenses, screens, sound units, and projectors, it

has become necessary to design and build special screen frames with built-in curves and angle tilting. After this new unit had been in operation a short time many exhibitors realized that due to the large screen frame, they had lost the use of their stages for other types of shows and productions. It then became necessary to consider flying these complete screen frame units safely, quickly and as economically as possible so that the show, whether motion picture or stage show would not be interrupted,


Because of the unusual type of frame construction and weight due to the large sized units, this required engineering technique and professional installation

skill. Before making these CinemaScope installations a thorough survey of the existing building conditions and the different problems that would be encounte ered during this new construction had to be made in order to give the exhibitor a complete and satisfactory operating job. This work should be done by coms petent engineers who are familiar with all phases of theatre construction and installation work, and includes the surveying and checking of existing gridiron conditions, present locations of counterweight sets to be moved to a new location, and available power specifications. One of the most important things to keep in mind at this time was the actual material and necessary construction required to give the owner the most for his money.

This preliminary work must also consider the design and reinforcing of the present screen frames with additional steel members to stiffen this frame and hold the required tilt and curve in the same position at all times and under all conditions, without the use of bow tension cables and other temporary Wall or floor bracing.

Two or three counterweights are generally required to fly these units and also help to give smooth and easy manual operation.
