  • Patent number: 10464728
    Abstract: The present invention is directed to flexible peelable/reseatable packages uniquely well suited for packaging convenience foods such as processed meats, cheeses and the like. The packages include a peelable/resealable interface formed from a pressure sensitive adhesive (PSA) which permit the packages to be re-sealed after their initial opening. There is also an absorbent non-woven strip which is inserted between the first and second wall panels near the PSA interface. During the opening of the package when the wall panels are forced apart in opposite directions, the absorbent non-woven strip cohesively ruptures and at least a portion of the strip remains bonded to each wall panel after the package has been opened. The absorbent non-woven strip absorbs water and/or fats, grease and oils from the food products before these materials can contaminate the PSA interface.

  • Patent number: 9981411
    Abstract: A structural polymeric composite includes a stiffening layer. The composite is made in a continuous extrusion process in which the stiffening layer is pulled through a cross-head die as a polymer is extruded over it. The layer includes a film or textile carrier, a filler of carbon fibers, fiberglass, organic fibers or minerals forming a mat. A binder may be dispersed over the mat and a second carrier applied. The mat is subjected to heat and pressure to soften the carriers and binder so they penetrate into the interstices of the filler and binds mechanically with them and the carriers and binder bind chemically with each other to form the stiffening layer. A polymer is then extruded over the stiffening layer, which may be used flat, provided with holes or punches for composite action with the polymer, formed into a profile, or segmented to provide spaced-apart stiffening layers.

  • Patent number: 9630360
    Abstract: In the pultrusion of reinforced plastic profiles in strand form, the strands of the reinforcement are brought together in a positioning device and subsequently embedded in the plastic. The pulling of the strands of the reinforcement through the positioning device leads to an unwanted contraction and uncontrolled positioning of the reinforcement in the plastic profile. The invention envisages forming the positioning device by multiple successive positioning means, of which at least some positioning means can be periodically moved forward in the direction of production and also moved back counter to the direction of production. As a result, there is an alternating tensioning and compression of individual regions of the reinforcement. This makes exact positioning of the reinforcement in the plastic profile possible and prevents contraction of the reinforcement.
