Question

Machine used for cutting straight lines in layout is

• A. Straight knife
• B. Rotary knife
• C. Water jets
• D. Laser knife

Hint:

• Straight Knife Cutting Machine Has a vertical reciprocating blade. Versatile for cutting straight lines and curves in multi-ply fabric lays. A workhorse in garment cutting rooms.
• Rotary Knife (Round Knife) Has a circular rotating blade. Good for long straight cuts and large curves.
• Laser Cutting High precision, good for intricate shapes and synthetics (edge sealing). More specialized.
• Water Jet Cutting Uses high-pressure water. More for industrial materials or specialized textiles.
• For general garment pattern cutting involving straight lines from a lay, the straight knife is a primary tool.

Answer 1

The Correct Option is A

A straight knife is the most commonly used cutting machine in the garment industry, particularly for cutting straight lines during the layout of fabrics. It consists of a vertical blade that moves rapidly up and down, allowing it to cut through multiple layers of fabric in a straight path with high efficiency and accuracy.

Why Not the Others?

Rotary knife: Better suited for curved cuts and small production runs; not ideal for long, straight-line cutting.

Water jets: Used for cutting non-textile materials like metal or glass, not typically for fabric in garment layout.

Laser knife: More advanced and expensive, mainly used for intricate designs or synthetic fabrics, not primarily for straight-line layout cutting.

Summary:

Straight knife is the most efficient and widely used machine for cutting straight lines in the layout process, especially in mass production settings like garment factories.
