Abstract: Apparatus for directing and feeding wire (W) such as for a welder includes first and second, generally planar, guide plates (108) which are slid in a direction parallel to the movement path of the wire (W) into a slit (74) of a mount (68) and a slot (64) of an adapter element (44). A driven roll (20) penetrates an opening (112) in the first guide plate (108). A pressure roll (82) is pivotably mounted to mount (68) between a drive position where it penetrates an opening (112) in the second guide plate (108) and sandwiches wire (W) against the driven roll (20) and a disengaged position. The pressure roll (82) is removably held in the drive position by abutment of a washer (104) with the bracket (84) to which pressure roll (82) is rotatably mounted. The washer (104) is slideable upon a shaft (98) and biased toward the bracket (84) by a spring (106), with the shaft (98) being pivotably mounted to a connecting block (24) between a latched and unlatched position.

Abstract: A fastener tape for use in the manufacture of reclosable plastic bags is provided. The fastener tape comprises an intermediate layer and a reclosable fastener profile thereon. The intermediate layer includes three layers of co-extruded plastic, with not more than 4% EVA as the outer two layers and HDPE as the middle layer. The intermediate layer is folded so as to bring portions of the intermediate layer into an opposing relationship. These opposing portions are then sealed together by a pair of seal bars. By carefully controlling the sealing temperature, a consistent peel seal is created between the opposing portions of the intermediate layer without the need for an adhesive.

Abstract: A method and apparatus for providing welding type power is disclosed. The power source is capable of receiving any input voltage over a wide range of input voltages and includes an input rectifier that rectifies the ac input into a dc signal. A dc voltage stage converts the dc signal to a desired dc voltage and an inverter inverts the dc signal into a second ac signal. An output transformer receives the second ac signal and provides a third ac signal that has a current magnitude suitable for welding, cutting or induction heating. The welding type current may be rectified and smoothed by an output inductor and an output rectifier. A controller provides control signals to the inverter and a controller power supply can also receive a range of input voltages and provide a control power signal to the controller, and a voltage independent of the input voltage.

The balanced flow of positive and negative ions are directed toward a workspace or target located in the gaseous environment and downstream from the ionizer. The ionizer includes a corona electrode, a counterelectrode, a corona-free dc bias electrode, and a control circuit. The corona electrode has a negative polarity. The counterelectrode has an ion collecting surface. The corona-free dc bias electrode has a positive polarity. The control circuit controls the output of the corona-free electrode so as to cause a balanced flow of positive and negative ions to be emitted from the ionizer and directed towards the workspace or target. In this manner, a static-free environment is created at the workspace or target.

Abstract: An apparatus and high speed process for heating and stretching a film having a bridle mechanism comprising a first heated roll and a second heated roll. The film is stretched as the film is transferred from the first heated roll to the second heated roll which rotates at a speed greater than the speed at which the first heated roll rotates. The film is fed into the bridle mechanism at a rate of about 1,500 fpm to about 2,500 fpm wherein it is stretched to a length that is up to about 450% greater than its initial, pre-stretched length. The increased contact between the large diameter heated rolls and the film and the short draw gap between the two heated rolls result in a highly stretched film having minimal neck-in.

Abstract: A process for preparing a PET flake mixture for use in connection with the fabrication of high-performance plastic strapping comprises the steps of initially collecting post-consumer and non-post-consumer PET materials having an initially wide range of relatively low intrinsic viscosity (IV) values with a relatively low average intrinsic viscosity (IV) value, and processing the same through solid state polymerization (SSP) so as to obtain a wide range of relatively high intrinsic viscosity (IV) values with a relatively high average intrinsic viscosity (IV) value. The initially collected materials are chopped into flakes and chunks, and the chunks are removed by a suitable destoner so as to render the remaining mixture comprised substantially entirely of flake materials or segments.

Abstract: A hot melt adhesive dispensing nozzle or die assembly spans two adjacent adhesive material valved inlets. One of the valved inlets is blocked off by means of the nozzle or die assembly, while the other adhesive material input or valved inlet is in effect split into two equal laterally separated output arrays of dispensing nozzles so as to provide for a void in the dispensing or deposition pattern at a predeterminedly desired location. The nozzle or die assembly comprises unique structure for ensuring that the hot melt adhesive material is able to be conducted to the remote one of the laterally separated array of dispensing nozzles. In addition, the two laterally separated arrays of output dispensing nozzles together comprise the same number of conventional non-split output dispensing nozzles operatively associated with each adhesive material input or valved inlet such that the volume flow rate through each one of the individual dispensing nozzles remains the same.
