Abstract
A circular knitting machine is described whose components can be adjusted to meet an order with the aid of adjustment data sets stored in a data memory and which relate to a predetermined knitting structure, yarn type, yarn thickness and quality of the knitwear to be produced and preferably arise from knitting processes already carried out on the circular knitting machine. A basic adjustment is preferably first effected on the basis of the adjustment data and can be followed by a fine adjustment with a central adjusting device for the loop size, until the desired quality is attained. (FIG. 1).
Claims21
A circular knitting machine for producing a knitwear with selectively different characteristics, comprising:
- a control device (21) having a keyboard (42), a display unit (41) and a memory for data pertaining to the knitwear and a plurality of components in the form of a cam arrangement (36) having individually adjustable cam parts forming knitting points, a central adjusting device for simultaneous adjustment of a loop size at all knitting points, and a yarn feed device having positive yarn feed rolls (10) and at least one drive device (8, 9) for these rolls adjustable to a selected yarn feed amount, wherein said control device (21) is arranged for entry and storing and for output and display of a plurality of adjustment data sets (FIGS. 6, 7) for the components, and wherein each adjustment data set leads to knitwear with predetermined characteristics.
A method of adjusting a circular knitting machine for producing a knitwear with selectively different characteristics and comprising a control device (21) having a memory for data pertaining to the knitwear and a plurality of components in the form of a cam arrangement (36) having adjustable can parts, a central adjusting device for simultaneous adjustment of a loop size and a yarn feed device having positive feed rolls (10) and at least a drive device (8, 9) for these rolls (10) for adjusting a selected yarn feed amount, said method including the steps of storing a plurality of adjustment data sets (FIGS. 6, 7) in said memory, each adjustment data set including adjustment data for so adjusting said components that knitwear of predetermined characteristics is knitted, providing first a basic adjustment of said components by using a preselected adjustment data set, determining a square meter weight of the knitwear arising with this basic adjustment and effecting a fine adjustment of the components in case of deviation from a prescribed square meter weight, until the quality of the knitwear corresponds substantially to a prescribed square meter weight.
