An applicator head for applying an adhesive tape on a surface or substrate, wherein the adhesive tape comprises a material and at least one removable liner, the applicator head comprising: an application tip; a cutting mechanism positioned adjacent an outer most point of the application tip; a positioning device is configured such that the cutting mechanism severs the material while maintaining the at least one removable liner intact.

An automated unspooling mechanism capable of dispensing of knitting material strands in a dynamically-controlled tension on a knitting machine. An unspooling device is configured to sense the tension of a strand fed to the knitting machine, and responsively adjust the strand deployment speed to avoid too little or too much strand dispensing without interrupting the knitting process. The unspooling device includes a variable motor drive that can rotate the strand package in various speeds, and a spring arm trigger that can sense the current tension of the dispensed material. The spring arm trigger can vary its arm position based on the sensed tension. The arm position is then processed and converted to a signal to vary the motor speed. Therefore, the deployment speed of the strands can be dynamically controlled based on a sensed tension of feeding the strand.

Disclosed are systems and methods for feeding welding wire for welding-type applications. The wire-feeder system comprises a spool hub configured to support a wire spool and a multiple-angle hub stand. The multiple-angle hub stand is configured to support the spool hub and the wire spool relative to a mounting surface. The multiple-angle hub stand comprises a lock configured to secure the spool hub relative to the mounting surface at one of a plurality of selectable angles.

In an adjustment device for a frictional force adjustment portion in a section, an inner circumferential portion of the section includes: a support hole formed from rolling bearings at both ends; a frictional force generation portion configured of a brake shoe, a coil spring, and a hexagon socket set screw and generates a frictional force against a rotary shaft inserted into the support hole; and a frictional force adjustment portion configured of the hexagon socket set screw and adjusts the frictional force in the frictional force generation portion. The adjustment member driving actuator adjusts the frictional force of the frictional force adjustment portion by rotating normally and reversely the adjustment member such that the frictional force in the frictional force generation portion of the section falls within a predetermined range.

A method and a device for optimal use of windable material during winding up onto and/or unwinding from storage drums operates in conjunction with feeding to winding machines. The windable material can be a textile web, a fabric web, a wire or the like. A counterforce necessary for keeping the tension force acting on the windable material constant is maintained until all of the windable material has been fed into subsequent processing. The counterforce may be maintained by a connecting element that is connected to the windable material and to the storage drum, is able to be wound up, and is of lower quality than the windable material. In the device, controllable means generate the counterforce counteracting the tension force until all of the windable material has been drawn into the subsequent processing device.
