Question

In \(\underline{\hspace{2cm}}\) weft knitting machine, the needles in the two beds are not face to face but needles in one bed are in between the needles of the other bed.

• A. Single jersey circular machine
• B. Rib knitting
• C. Interlock knitting
• D. Purl knitting

Hint:

Remember the two main double-jersey gatings: - Rib Gating: Needles are face-to-face (opposite). Produces rib fabrics. - Interlock Gating: Needles are staggered (in-between). Produces interlock fabrics.

Answer 1

The Correct Option is C

Step 1: Understand the question. It describes a knitting machine with two beds of needles (e.g., a cylinder and a dial). The key feature is the needle arrangement: they are not directly opposite each other ("face to face"), but are staggered or "in between." This is known as interlock gating. 
 

Step 2: Analyze the gating of different knitting machines. 
- Single jersey circular machine: Has only one set (bed) of needles, so this option is incorrect. 
- Rib knitting: Uses two beds of needles (cylinder and dial) that are arranged directly opposite each other. This is called rib gating. When needles from both beds are activated, they move towards the space between opposing needles. 
- Interlock knitting: Uses two beds of needles in an "interlock gating" arrangement. The needles are staggered, so a needle from one bed is directly opposite a space between two needles on the other bed. This requires two separate cam systems for each bed, selecting long and short needles. 
- Purl knitting: Uses double-headed latch needles that can transfer between two beds. This allows for purl stitches (loops to the front and back in the same wale). The gating is typically rib gating. 

Conclusion: The staggered, non-face-to-face needle arrangement is the definition of interlock gating, used in interlock knitting.
