The GBPI 10-Piece Rotary Drum Tensile Specimen Cutter is a specialized laboratory specimen preparation instrument developed specifically for precision strip cutting of flexible plastic films, laminated barrier packaging, aluminum-plastic composites, and paper membranes. Designed in strict compliance with the sample preparation requirements of ASTM D882, ISO 527-3, GB/T 8808, and GB 13022, this heavy-duty rotary cutter provides testing laboratories with consistent, burr-free specimens required for accredited tensile and elongation testing.
Specimen edge quality is one of the most significant sources of scatter in thin film tensile testing. Minor micro-notches, micro-tears, or width inconsistencies introduced by standard razor blades or hand scissors act as severe stress concentration points, causing premature specimen fracture and artificially depressed tensile strength and elongation values. Operating as a dedicated tensile sample cutter, the GBPI rotary cutter employs a cylindrical multi-blade drum fitted with ten ultra-sharp, ground alloy steel circular cutting knives spaced with micrometer accuracy. As the operator turns the counterbalanced rotary arm, the drum smoothly traverses the clamped film sheet against precision hardened guide slots, severing up to ten standard 15 mm × 210 mm specimen strips simultaneously in one rapid, repeatable sweep.
Ten Identical Strips in a Single Stroke
By cutting ten test strips concurrently, the cutter dramatically shortens daily sample preparation times for high-volume converting facilities. All ten specimens possess identical width tolerances (±0.1 mm) and perfectly parallel longitudinal edges, guaranteeing statistical consistency during multi-sample tensile and 180° peel testing.
Rigid Construction & Operator Safety
The instrument features a vibration-absorbing heavy-gauge steel base with non-slip leveling feet. An integrated mechanical clamp secures the test film smoothly across the cutting platen to prevent wrinkling. The cutting drum is fully shielded within an articulated safety guard, protecting operator hands while maintaining full line-of-sight during the cutting stroke.
The system requires zero electrical or pneumatic connections, making it an indispensable, maintenance-free companion for any tensile testing laboratory.
