I'm on the lookout for a single feed machine designed for small diameter cylinders, specifically in the range of 11" to 13". The machine will primarily be used for processing chunky yarns, so it's essential that it can handle a variety of thick and textured materials. I'd appreciate it if you could provide details regarding the specifications, capabilities, and any available models that fit these parameters. Additionally, information on pricing, lead times, and any warranties or support services would be helpful as I make my procurement decision. Thanks!
