It was produced by Caravel Films of New York. The Model 31 is equipped with one to four magazines and a gas-heated metal pot with microtherm temperature control, making it ideal for high-speed production. The Model 32, with additional auxiliary magazines, offered greater versatility and capacity. Key features include a one-turn shift for magazine changes, a sensitive and ergonomic keyboard, and various safety mechanisms that prevent errors and protect the machine. Designed for easy maintenance, allowing operators to perform adjustments and cleaning without leaving their seat. Additional production aids like a self-quoting device and cooling mechanisms further enhance efficiency. Overall, Linotype machines are praised for their durability, cost-effectiveness, and ability to deliver high-quality compositions with minimal downtime. 00:00: Introduction to the Linotype Model 31, a single distributor composing machine, highlighting its features and configurations with one to four magazines and corresponding supporting frames. 0:39: Description of the machine’s standard equipment: a one-turn shift for shifting magazines, a gas-heated metal pot with microtherm temperature control, and a four-mold disc. 1:17: Introduction of the Model 32, which is similar to the Model 31 but with auxiliary magazines and a separate auxiliary keyboard. It is highlighted as a high-speed, efficient machine for composing different types of print material. 1:56: Emphasizing the importance of time in production, the Linotype machines help maintain high-speed production and minimize downtime, making them reliable in the composing room. 2:16: Demonstrating how the machine is designed for safety and efficiency, such as how the magazines are positioned to avoid operator accidents and how they are easily placed into the machine. 3:06: Explanation of the one-turn shift process for changing magazines quickly and safely. Distributor screw guard prevents malfunction when matrices are still being distributed. 4:00: Keyboard is precision-engineered for comfort, with a focus on ease of adjustment and accessibility. 5:19: The operator can perform maintenance easily by removing key parts such as the cam, rubber roll shaft, and key assembly without leaving their seat. It shows how these parts can be cleaned and adjusted. 7:00: Ability to maintain precision during the casting process with features such as adjustable matrix tension, safety features like the short line safety, and pot advance safety, which prevent accidents during production. 9:00: Safety mechanisms preventing operator errors and machine damage, including the mold slide safety, which stops the machine from operating if a wrong mold is used. 10:23: Advanced temperature control in the metal pot, including the microtherm system and its efficient use of gas and electric heating, ensuring consistent casting quality. 12:08: Shows how the ejector mechanism works to remove slugs from the mold with precision and accuracy. Also, it highlights the trimming knife block that can be easily adjusted for different slug sizes. 13:20: Discusses the distribution system, which is designed to prevent misalignment at critical transfer points, ensuring the longevity of the machine and accurate matrix handling. 16:00: Describes the Model 32's additional matrix capacity, featuring an automatic system for matrix distribution. 17:16: Optional production aids: the self-quoting device, the six-mold disc, and Thermablow air cooling device. 19:02: Conclusion: the versatility, safety, and cost-effectiveness of Linotype machines. Linotype offers high production value, reduced maintenance downtime, and greater longevity, providing a strong return on investment.
