Process for knotting roving packages

A process for knotting roving packages, comprising steps of:

• arranging a plurality of roving packages in a single layer or multiple layers;
• dividing all roving packages into at least one group of roving packages;
• selecting, from each group of roving packages, two roving packages as a starting roving package and an ending roving package;
• successively connecting all roving packages in each group of roving packages from the starting roving package to the ending roving package;
• and, connecting an inner fiber of a roving package other than the starting roving package and the ending roving package in each group of roving packages to an outer fiber of a previous roving package and connecting an outer fiber of this roving package to an inner fiber of a next roving package, or connecting an outer fiber of a roving package other than the starting roving package and the ending roving package in each group of roving packages to an inner fiber of a previous roving package and connecting an inner fiber of this roving package to an outer fiber of a next roving package;
• wherein,
• when all roving packages are arranged in a same layer, all the roving packages form an rectangle having M rows and N columns, wherein both M and N are integers greater than 1, and all the roving packages are divided into X groups, wherein X is an integer less than or equal to (M*N)/2;
• and
• when all the roving packages are arranged in Y layers, the roving packages in each layer form an rectangle having M rows and N columns, wherein M, N and Y are all integers greater than 1, and all the roving packages are divided into X groups, wherein X is an integer less than or equal to (M*N*Y)/2.

• wherein,
• when the roving packages in a group belong to a same layer, the roving packages in this group form an rectangle having M rows and N columns, wherein both M and N are integers greater than 1;
• when M is an even number, a roving package in the first row and the first column is a starting roving package, and a roving package in the Mth row and the first column is an ending roving package;
• and, when M is an odd number, a roving package in the first row and the first column is a starting roving package, and a roving package in the Mth row and the Nth column is an ending roving package.
