Abstract: Relative movements of a tool and a workpiece are controlled by moving a tool axis in all spatial dimensions for the material-removal machining of the workpiece to produce a desired target contour of the workpiece by a sequence of relative movements along a tool trajectory of the tool. The tool trajectory is subdivided into a multiplicity of target segments along which the tool is in engagement with the workpiece so that the orientation of the tool axis is consistent within a target segment, while the orientation of the tool axis is variable over the entire tool trajectory, and a respective and point of a target segment is connected by a linking pivot movement, during which the tool does not engage the workpiece and in which the orientation of the tool axis is altered, with a starting point of a further target segment.

Abstract: A device for fitting articles including rivets, buttons and the like, to a fabric, comprising a lower tool serving as an abutment for an article, and a ram executing a riveting stroke. A lower end of the ram joins with an upper tool for impinging upon an upper portion of the article and for urging the article against the lower tool upon execution of the riveting stroke. A rotatably driven cam disc urges an upper end of the ram for controlling travel movement of the ram. A clamp is carried by the bottom end of the ram for movement in synchronism with the ram. For finger protection, the device is operative to stop the clamp in a position spaced from the lower tool during a first lowering movement.

Abstract: A machine for the attachment of buttons, rivets or the like, preferably to articles of clothing, which buttons, rivets or the like consist of an upper portion and a lower portion, a material held between an upper clamping jaw and a lower clamping jaw being punched by actuation of a ram, and, after movement of a slide having an upper tool and a lower tool, the button portions disposed therein being positively connected to one another by ram actuation by virtue of the upper and lower tools being brought towards one another. In order to be able to carry out the punching of the article of clothing which is necessary before the attachment of the object, using the same machine and without changing the position of the article of clothing, an attachment tool (36) at the end of the ram is disposed, in the hole punching disposition (FIG. 3), in coaxial alignment with a hole punching tool (26).

Abstract: A modular shutter is assembled of prefabricated components and of yard goods or piece goods which are cut to size at the locale of use. The components of the shutter include two upright guide rails for the end portions of a curtain of upwardly and downwardly movable as well as tiltable slats, a horizontal main shaft between the upper end portions of the guide rails, a housing mounted on top of each guide rail and having bearings for the corresponding end portions of the main shaft, a motor or a crank drive for rotating the main shaft clockwise or counterclockwise, and combined lifting and tilting mechanisms in the housings. Such mechanisms have lifting bands which are connected with the end portions of the slats to effect upward or downward movements of the slats in response to rotation of the main shaft in one or the other direction, and tilting bands which change the angular positions of the slats in response to selected rotation of the main shaft.

Abstract: A venetian blind wherein the slats are moved up and down by means of cords or strips in response to rotation of a shaft in clockwise and anticlockwise directions. The shaft actuates a mechanism serving to turn the slats between open and closed positions and through intermediate positions in which the slats are partly open. The mechanism is caused to automatically maintain the slats in the open positions during upward movement of slats and in the intermediate positions when the slats move downwardly. The slats can turn between the open and closed positions when the venetian blind is fully extended. Yieldable detents are provided to releasably hold the slats in the open, closed or intermediate positions.
