Stokes Model 557

Quality Workmanship you can Trust

The Stokes Model 557 is a heavy-duty rotary press designed for single sided operations with a maximum of 23 tooling stations, 3 1/4" fill and compact sizes up to 3 1/2".

Construction Features

Mainframes and crossheads are sturdily machined castings and cams. Pressure rolls are hardened steel for superior tool and part life. The two piece head is precision machined to ensure accurate tool alignment and guarantee the die table is precision ground and polished.

Three Point Transit Leveling

Arrangement permits simple and precise setup of the feed frame. No resetting of feeder is required.

Stainless Steel Hopper

This feature provides vertical adjustment and lock provision.

Dust Removal Suction Nozzles

Nozzles are positioned above and below the die table for clean operation.

Adjustable Upper Roll

The roll permits compacting of tablets at various points in the die in order to extend die life. This feature minimizes capping and laminating of tablets.

Handwheel Control

Controls press speeds, fill and pressure settings.

Keywayed Upper Punch Sockets

Provides punch alignment when producing tablets of irregular shape.

Pin Type Transit Level Feeder

The feeder funnels materials directly over the die cavity. Stationary pins cause a cascading action that improves filling of the dies for accurate tablet weight. This feeder also has an adjustable gate that maintains fluidity tunnel of granulation and prevents packing in the frame.

Safety Features

Locking the lever in a disengaged position reduces the likelihood of accidental starting. All guards are interlocked to prevent access during operation.

Adjustable Spring Release

The adjustable spring release maintains desired pressure and helps protect tools against damage or breakage in case of accidental overload. Pneumatic release is optional.

Lower Punch Adjustment

At ejection, this feature allows for the use of reworked tooling.
