Knit fabric is a manufacturing system that turns thread into fabric by forming knitted loops by interlinking them. There are two systems to produce knitted loops: weft and warp knitting. In knit fabric made with weft knitting, the knitted loop is made horizontally with a single thread that feeds all the needles. This rectilinear weft knitting loom manufactured in Olot is specialised in producing berets and is proof of the diverse range of products which have historically been manufactured in Catalonia using the knit fabric technique.
