The present invention relates to devices and components for milking apparatus, in particular to milk extracting devices. Especially it relates to components of such devices such as liners (). The novel devices include a material, selected from the group consisting of thermo-plastic elastomers, as defined in ISO 18064, plasticized PVC, Vinyl TPE, the material exhibiting the following properties: a hardness between 25 shore A and 50 shore D; a Young's modulus between 0.1 MPa and 50 MPa; a tensile strength above 0.5 MPa; and a minimum elongation of 50% without breakage.

Milking devices

An arrangement is provided in a milking system for simultaneous milking of a plurality of milking animals, wherein the milking system comprises a plurality of milking positions (P-P) and an arrangement for establishing identities of and expected milking times for the milking animals. Each of the milking positions is provided with teat cups, which are attached to the teats of a milking animal and are connected to a source of vacuum to milk the milking animal. The inventive arrangement comprises means () for determining a milking position, at which the milking animal having the longest expected milking time is present, based on the established identities and expected milking times; and a device () for performing an action with respect to the milking system in response to the determination.

Arrangement and method in a milking system

A milking device includes at least a teat-receiving flexible sleeve, adapted to be positioned on/over a teat. A first portion thereof includes a material, selected from the group consisting of thermo-plastic elastomers (TPE), as defined in ISO 18064, and a second portion thereof includes a material selected from the group consisting of thermoplastics. The method of making a milking device, in particular a teat cup liner, is a molding process carried out in two or more steps. In the first step, a thermoplastic, preferably polypropylene (PP) or polyamide (PA), is injected in a mold defining only those portions of the device that are to exhibit a higher stiffness or rigidity, such as couplings. The stiffer parts, are demolded from the mold, and placed in a second mold, into which, as a second molding step, a suitable TPE is injected. Further steps can be performed if required by the design.
