A tissue modification apparatus includes at least a first plurality of grippers aligned in a plane adapted to secure a first edge of a patch of tissue. The plurality of grippers are each secured to a first force actuator. The first plurality of grippers are each adapted to pivot relative to the first force actuator about an axis perpendicular to the plane. In some cases, a plurality of grippers are attached to a force actuator by a passive force transfer mechanism. In some cases, individual force actuators are attached by pivoted connections to individual grippers. Methods of treating tissue can secure tensioned tissue to a frame to retain the tension during a treatment (e.g., cross-linking the tissue with a chemical cross-linker).

The present invention relates to an elongated pelt board for accommodating an animal pelt. The pelt board comprises a first wall element, a second wall element being spaced apart from the first wall element in the first radial direction, a third wall element and a fourth wall element being spaced apart from the third wall element in a second radial direction. The wall elements together define a cavity along a longitudinal direction. The wall elements defining a contracted state in which the first and second radial distances are reduced, and an expanded state in which the first and second radial distances are increased. The pelt board further comprising an elongated core element being movable in relation to each of the wall elements. The elongated core element allows the wall elements to selectively define the contracted state or the expanded state by moving the elongated core element in the longitudinal direction.

An elongated pelt board for accommodating an animal pelt. The pelt board defines a blunt end and an opposite pointed end and a longitudinal direction. The pelt board further defines a first radial direction perpendicular to the longitudinal direction and a second radial direction perpendicular to the longitudinal direction and the first radial direction, said pelt board comprising a first part at said blunt end and an opposite second part at said pointed end. The first part comprises a first wall element and a second wall element. The first and second wall elements are of identical configuration. The first wall element and said second wall element define a contracted state and an expanded state.

A stretching apparatus for stretching a pelt on a pelt board, wherein the pelt has a substantially tubular shape defining an inwardly oriented leather side, an outwardly oriented fur side, a nose end, a rear end and a pair of front leg cavities. The pelt board defines a top end for accommodating and fixating the nose end of the pelt, a circumferential wall for facing the inwardly oriented leather side of the pelt and a base end located opposite the top end. The stretching apparatus comprises a holding device for holding the base end of the pelt board, and a stretching device having a pair of stretching members. Each of the stretching members are adapted in order to be inserted into a respective front leg cavity of the pelt and the stretching device is movable in a direction towards the holding device for stretching the pelt.
