SPI (Acute round point)

Needles with a acute round point "SPI" that is very slim, allow accurate piercing of densely woven and coated materials. Additionally, this point shape enables you to get exact seam appearance while avoiding seam puckering.

SCHMETZ SERV 7

Besides fabric damage, skip stitches are a problem that frequently arises when sewing elastic material. To prevent them, SCHMETZ developed the SERV 7 needle. This specially shaped needle is made for almost all needle systems, with all the main point shapes and in all current needle sizes.

The main distinguishing features of the SERV 7 design are the hump scarf that makes a particularly large loop of thread which can be more easily caught by the point of the hook and the blade reinforcement, that ensures the extraordinarily high stability of the needle. To produce the smallest possible stitch holes and optimise fabric displacement, the SERV 7 design thus often allows the use of a needle one size smaller without any reduction in the stability of the needle.

SERV 7 needles have a 15 % reinforcement, and as much as 20 % in some needle sizes. Therefore, the needle is especially stable and far less likely to “bend”. Neither the hook or looper nor other machine parts, e.g. the throat plate, are damaged.
