A method for feeding a thread at a preset drawing to a textile machine includes a first feeder which sends the thread to the textile machine and a second feeder arranged spaced from the first feeder and which sends such thread to the latter, each feeder having a rotary member on which there is partly wound the thread before the feeding thereof and a speed sensor adapted to detect the rotational speed of such rotary member and a tension sensor to detect the tension of the thread exiting from each feeder. Controlling drawing the thread sent to the textile machine by controlling and adjusting the ratio between the rotational speed of the rotary member of the first feeder and the rotational speed of the rotary member of the second feeder.

Methods and apparatus to control advancement of a welding electrode wire for arc ignition are disclosed. An example electrode wire feeder includes a wire feed motor to advance electrode wire to a welding torch, a temperature monitor to determine a temperature of the electrode wire using at least one of a temperature measurement or a thermal model, and a motor controller to control a run-in wire speed based on a temperature of the electrode wire.

Various embodiments are described that relate to dispensing from an apparatus. The apparatus can be a cable dispensing apparatus that is attached to a vehicle. As the vehicle travels, the apparatus can lay or retract cable. The rate of this laying or retracting can be based, at least in part, on a travel condition of the vehicle.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.

The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. Aspects of the methods for assembling elastomeric laminates may utilize elastic strands supplied from beams that may be joined with first and second substrates, and may be configured to carry out various types of operations, such as bonding and splicing operations.

A method for feeding elastic threads in a process for the production of layered composite articles includes: feeding at least one elastic thread along a path extending from a reel of an elastic thread up to a joining zone with at least one web material. Feeding the elastic thread along the above path includes: giving the elastic thread a first percentage elongation along a first section of the path extending between the reel and a control zone; giving the elastic thread a second percentage elongation along a second section of the path extending between the control zone and the joining zone. The second percentage elongation is greater than the first percentage elongation and a length of the first section is greater than a length of the second section.
