Technical details and manufacturing context for Sammying and Setting Machine

Definition
The Sammying and Setting Machine is a critical component within the Integrated Leather Processing System responsible for mechanically stretching leather hides after tanning to eliminate wrinkles, ensure uniform thickness across the entire surface, and properly set the grain pattern. This process prepares the leather for subsequent finishing operations by creating a smooth, consistent substrate.
Working Principle
The machine uses a series of rollers, clamps, or tensioning mechanisms to apply controlled mechanical force to the leather hide, stretching it in multiple directions while maintaining consistent pressure. This action aligns collagen fibers, removes residual moisture-induced shrinkage, and sets the desired dimensions before the leather fully dries or undergoes chemical setting treatments.
Common Materials
Stainless Steel, Hardened Alloy Steel, Synthetic Rubber
Technical Parameters
  • Maximum working width of leather hide that can be processed (mm) Standard Spec
Components / BOM
Engineering Reasoning
0.8-1.2 MPa hydraulic pressure, 20-40 rpm roller speed, 50-80°C platen temperature
Hydraulic pressure exceeding 1.5 MPa causes seal rupture, roller speed below 15 rpm creates permanent creases, platen temperature above 90°C denatures collagen fibers
Design Rationale: Leather's viscoelastic properties (Young's modulus 100-500 MPa, Poisson's ratio 0.4-0.5) require controlled stress-strain relationships; exceeding yield strength (5-15 MPa) causes permanent deformation; thermal degradation occurs above collagen's denaturation temperature (65-70°C)
Risk Mitigation (FMEA)
Trigger Hydraulic fluid contamination exceeding ISO 4406 18/16/13 cleanliness level
Mode: Servo valve spool sticking causing asymmetric roller pressure distribution
Strategy: Install 3 μm absolute filtration with differential pressure monitoring and automatic bypass
Trigger Cyclic loading exceeding 10⁶ cycles at 0.8-1.2 MPa stress range
Mode: Fatigue crack propagation in roller bearing housings at stress concentration points
Strategy: Finite element analysis-optimized fillet radii (minimum 5 mm) with shot peening to induce 400-600 MPa compressive residual stress
