  • Publication number: 20180317453
    Abstract: A therapeutic shoe for cloven-hooved lactating animals protects a diseased or injured hoof from the external environment to promote healing. The shoe is notionally divided into four parts: a sole portion for supporting the undersides of the medial and lateral claws; a vamp portion connected to the sole portion for at least partially enveloping the hoof wall between its toe, heel and coronary band; a quarter portion connected to the vamp portion for at least partially enveloping the front and lateral pastern sections; and a heel portion connected to both the vamp and quarter portions for at least partially enveloping the heel and the area beneath the dew claws. The material of the shoe at the heel portion is relatively more deformable than the material of the shoe at the sole, vamp or quarter portions thus avoiding the application of excess pressure to this sensitive area of the hoof anatomy.

  • Patent number: 7897006
    Abstract: A method of adhering a first material to a second material, which utilizes an anchoring adhesive applied to one or both of the materials as a plurality of isolated adhesive anchors having interstitial spaces between them, forming improved bonding sites for a bonding adhesive which is used to adhere the materials together. In the preferred embodiment the anchoring adhesive may be applied by a process similar to silk screening, whereby a mask or screen defines a plurality of adhesive-impervious portions which create the interstitial spaces and adhesive-pervious portions which allow adhesive to pass through the screen to create the adhesive anchors. The bonding adhesive is applied to the material over the cured adhesive anchors, which serve as high-adhesion bonding sites for the bonding adhesive.
