Abstract: Sample extraction or trimming from an end strip of an elongated formed metal that is coiled in layers within a tensioned metal coil resting on driven rollers. A cut channel is formed across the material width. In some embodiments the cut channel is formed between the rollers and by cutting at an angle relative to the coil outer surface. Coil weight and/or a coil tensioner mechanism inhibits coil relaxation along the cut channel by maintaining tension on wrapped layers against each other when the coil is unbanded for sample extraction. The coil is rotated so that the cut channel clears the rollers laterally. Material downstream the cut is then separated from the coil. After trimming and/or sample extraction the coil maintains rolled tautness for ease of rebanding.

Abstract: A cutter for cutting an end section of a coiled web. The cutter includes roller elements for rotating the coiled web and a carriage assembly that is moveable in a first direction relative to a frame. The carriage assembly includes a saw element for cutting the end section to form a strip, wherein the saw element is moveable in a second direction transverse to the first direction. The carriage assembly also includes a contact wall and a spaced apart rotatable peeler element for separating the outer wrap of the web. In addition, the carriage assembly includes first and second actuators for moving the peeler element to a first position wherein the end section and strip are both clamped between the peeler element and the contact wall. Further, the second actuator rotates the peeler element to a second position wherein the end section is not clamped while the strip remains clamped.
