Computer apparatus for checking the correctness of a loom adjustment

An apparatus for use in adjusting the setting of the warp handling mechanism of a loom having a plurality of back rollers that guide warp threads fed from a warp beam, said back rollers each being carried by a first roller bracket which is supported for horizontally adjustable movement by a respective second bracket, and each second bracket is supported for vertically adjustable movement by a third bracket, said apparatus comprising:

• storage means for storing data representing the desired loom settings for various types of fabrics, the desired loom settings including a desired horizontal position and a desired vertical position of said back rollers;
• detecting means for detecting actual loom settings, said detecting means including a plurality of light emitters and a plurality of light receivers for mounting on oppositing ones of said brackets to detect the relative movement of the brackets;
• a central processing unit connected to said storage means and said detecting means for comparing desired loom settings and actual loom settings and judging whether desired and actual loom settings coincide with each other;
• display means connected to said central processing unit for displaying the result of said judging;
• and
• an input device connected to said central processing unit for inputting desired loom settings into the storage means.

An apparatus for adjusting the setting of the warp handling mechanism of a loom, the apparatus comprising:

• storage means for storing data representing desired settings of said mechanism for various types of fabrics, said mechanism settings including the vertical and horizontal positions of at least one back roller than guides warp threads fed from a warp beam, said back roller being carried by a first roller bracket which is supported for horizontal movement by a second bracket which, in turn, is supported for vertical movement by a fixed third bracket;
• detecting means operatively coupled with said mechanism for detecting actual loom settings;
• judging means operatively connected to said storage means and said detecting means for comparing desired mechanism settings and actual settings and judging whether the desired and actual settings coincide with each other;
• and
• display means disposed in proximity to said mechanism for indicating when said mechanism is adjusted to said desired settings.
