Abstract
Abstract A method of selectively supplying fiber material from an output of a fiber bale opener to a plurality of fiber processing lines each formed of a series of fiber processing machines, includes the steps of removing fiber by the bale opener sequentially from bales of different fiber types; supplying predetermined fiber processing lines with predetermined types of fiber by the bale opener; sensing a fiber quantity requirement of the fiber processing line while being supplied with fiber by the bale opener while the latter simultaneously performs fiber removal from the bales of a predetermined fiber type; interrupting the fiber removal at that location of the bale opener where it is situated when the fiber processing line then supplied with fiber, signals satisfaction of fiber requirement; and resuming fiber removal of the predetermined fiber type at the mentioned location upon a signal for fiber requirement by the fiber processing line supplied at the time of interruption.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
158 words
A method of selectively supplying fiber material from an output of a fiber bale opener to a plurality of fiber processing lines each formed of a series of fiber processing machines, including the steps of removing fiber by the bale opener sequentially from bales of different fiber types; supplying predetermined fiber processing lines with predetermined types of fiber by the bale opener; the improvement comprising the steps of (a) sensing a fiber quantity requirement of the fiber processing line while being supplied with fiber by the bale opener simultaneously performing fiber removal from the bales of a predetermined fiber type; (b) interrupting the fiber removal at that location of the bale opener where it is situated when the fiber processing line then supplied with fiber, signals satisfaction of fiber requirement; and (c) resuming fiber removal of said predetermined fiber type at said location upon a signal for fiber requirement by the fiber processing line supplied in step (a).
Claim 2

Claim 3
Dependent Claim
30 words
A method as defined in claim 1, wherein step (b) comprises the step of interposing a short delay between signals indicating satisfaction of fiber requirement and interruption of fiber removal.
Claim 4
Dependent Claim
58 words
A method as defined in claim 1, further comprising the step of overriding steps (b) and (c) if, upon a signal of satisfaction of fiber requirement the bale opener is within a predetermined distance from a forward end of a bale group undergoing opening and proceeding with the opening of the last-named bale group until the end thereof.
Claim 5
Dependent Claim
186 words
In a fiber processing system including a bale opener having a carriage arranged for a back-and-forth travel in a path along a fiber bale series; a tower supported on the carriage and a cantilever mounted on the tower and arranged for vertical displacements with respect to the tower; an opening device supported in said cantilever and arranged for removing fiber from the bale tops during travel of the carriage; a plurality of fiber processing lines connected to an output of said bale opener; sensor means for determining fiber quantities in each said fiber processing line; a control device having an output connected to said bale opener for controlling the operation of the bale opener; said sensor means being connected to an input of said control device, the improvement comprising a first measuring means for determining a length position of said carriage along said path; said first measuring means being connected to an input of said control device; a second measuring means for determining a height position of said cantilever and said opening device; said second measuring means being connected to an input of said control device.
Claim 6
Dependent Claim
186 words
In a fiber processing system including a bale opener having a carriage arranged for a back-and-forth travel in a path along a fiber bale series; a tower supported on the carriage and a cantilever mounted on the tower and arranged for vertical displacements with respect to the tower; an opening device supported in said cantilever and arranged for removing fiber from the bale tops during travel of the carriage; a plurality of fiber processing lines connected to an output of said bale opener; sensor means for determining fiber quantities in each said fiber processing line; a control device having an output connected to said bale opener for controlling the operation of the bale opener; said sensor means being connected to an input of said control device, the improvement comprising a first measuring means for determining a length position of said carriage along said path; said first measuring means being connected to an input of said control device; a second measuring means for determining a height position of said cantilever and said opening device; said second measuring means being connected to an input of said control device.
Claim 7
Dependent Claim
36 words
A fiber processing system as defined in claim 4, wherein said first measuring means comprises a sensor mounted on said bale opener and a marker element stationarily positioned along said path and cooperating with said sensor.
Claim 8
Dependent Claim
41 words
A fiber processing system as defined in claim 4, further comprising a drive means for raising and lowering said cantilever; said second measuring means comprising a counter connected to said drive means and generating signals representing height positions of said cantilever.
Claim 9
Dependent Claim
18 words
A fiber processing system as defined in claim 4, further comprising a memory connected to said control device.
Claim 10
Dependent Claim
16 words
A fiber processing system as defined in claim 7, wherein said memory is a buffered memory.
