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".
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.
