A module for a fiber preparation machine is a self-supporting element having a cuboid shape with a length (L), a width (B) and a height (H), as well as at least two lateral walls extending in parallel respective planes and spaced apart by the width (B). A cross beam connects the lateral walls to one another. Each of the lateral walls is encompassed by a frame. A first leg of the frame is arranged along the plane of the respective lateral wall and a second leg of the frame is arranged at a right angle to the lateral wall and facing away from the opposite lateral wall. A fiber preparation machine includes a plurality of the modules interconnected together.

A take-off arm is provided for a bale opener for taking off fiber flocks from fiber bales. The take-off arm includes a housing, and a take-off unit having an axial length within the housing. A pressing element is connected to the housing via only load cells such that a contact force (F) of the take-off arm on the fiber bales is continuously measured by an evaluation of the load cells situated between the pressing element and the housing.

A process for calibrating the loading force of a breaker element of a bale opener on a bale group includes: (a) setting a force sensor used to measure the loading force at no load; (b) lowering the breaker element onto the bale group until reaching a loading force that is at least twice as high as an upper loading force at which the breaker element receives a lift command during normal breaking operation; (c) relieving the load on the breaker element; (d) setting the loading force at a negative value which includes signal distortion influences; and (e) lowering the breaker element until the loading force measured by the load sensor reaches at least the level of the upper loading force.

A bale opener for the take-off of fiber tufts from fiber bales includes a take-off tower, which is arranged on a horizontal drive or a rotating frame, and a take-off arm. The take-off arm is held on the take-off tower in a guide so as to be vertically adjustable. A single lifting spindle having a longitudinal axis in the movement direction of the take-off arm is provided for the vertical adjustment of the take-off tower. The lifting spindle is fastened on the take-off tower and the take-off arm is connected to the lifting spindle via a nut.

A hair stylist device comprises a top and bottom board, each having a plurality of opposed bristles for retaining strands of bulk artificial or commercial hair therebetween for performing hairstyling operations, and including a hinge mechanism for opening and closing the boards around the bulk hair retaining it loosely but securely, while allowing the removal of strands of bulk hair without opening the device providing optimal gripping ability to the bulk hair while permitting removal of hair without unnecessary loss. The board inner surfaces each may have a generally planar pad with plural embedded bristles extending in a direction perpendicular to one surface of the pad. A longitudinal hinge connects the two boards to each other and a lock can secure the opposite longitudinal ends to each other. Compartments disposed at a surface of the boards provide storage for any necessary accessories required for the braiding or weaving process.
