  • Patent number: 4266411
    Abstract: A warp knit machine produces patterned plush-loop warp knit fabric and includes a row of hooked needles, a pillar bar for forming interlaced adjoining chains of the ground fabric and an inlay bar for laying inlay thread into the ground fabric. Each needle has a set of pile-thread guiders swingably mounted between non-selected and selected position. A guide comb structure comprises a row of blades defining first inter-blade gaps alternating with second inter-blade gaps. All pile threads are guided through the first gaps, but the selected pile threads differently located in the gaps. During certain phases of operation, the needles extend through the second gaps, and also a row of pile-thread-laying sinkers pass through the second gaps. The guide-comb structure is shogged to overlap selected pile threads, which the pile-thread sinkers then lay into the needle hooks. Also, the guide-comb structure is so configured that it underlaps the non-selected pile threads beneath the needles.
