A device for changing operative portions for tobacco industry machines including a receiving portion made in a structural part of a tobacco industry machine; a plug member attached to an operative portion of the tobacco industry machine, a locking member, housed in the structural part of the machine and configured to adopt a locked position, where it locks the plug member in the receiving portion, and a released position, where it releases the plug member from the receiving portion and actuating means acting on the locking member at least to move the locking member from the locked position to the released position.

Methods and apparatuses for aligning a first hole in a first panel with a second hole in a second panel to define a through-hole. A wall that defines the second hole is gripped from within the through-hole to pull the second panel towards the first panel and thereby establish a clamp-up of the first panel and the second panel.

Methods and apparatuses for providing a clamp-up are provided. The methods and apparatuses include reaching through a first hole in a first part to grip a wall that defines a second hole in a second part to thereby pull the second part against the first part.

Methods and apparatuses for providing a clamp-up are provided. An apparatus for forming a clamp-up comprises an end effector. The end effector is positioned at a first side of a panel joint and applies a first clamp-up force to a first panel of a panel joint and an equal and opposite second clamp-up force to a second panel of the panel joint to provide the clamp-up.

A shank-fastener apparatus (100) comprises a shank-fastener housing (170), a shank-fastener turret (102), an indexing-pin assembly (103), a drill (104), and a shank-fastener delivery assembly (105). The shank-fastener turret (102) is supported by the shank-fastener housing (170) and is selectively rotatable relative to the shank-fastener housing (170) about a shank-fastener-turret rotation axis (A). The indexing-pin assembly (103) is supported by the shank-fastener housing (170) and is selectively movable relative to the shank-fastener housing (170) between an indexing-pin-assembly extended position and an indexing-pin-assembly retracted position along an indexing-pin-assembly axis (B) that is parallel to the shank-fastener-turret rotation axis (A). The drill (104) is supported by the shank-fastener turret (102) and is selectively movable relative to the shank-fastener turret (102) along a drill axis (C) that is parallel to the shank-fastener-turret rotation axis (A). The shank-fastener delivery assembly (105) also supported by the shank-fastener turret (102).

A receiver-fastener apparatus (200) comprises a receiver-fastener housing (270), a receiver-fastener turret (202), an indexing-collet assembly (203), an anvil (204), a receiver-fastener delivery assembly (205), and a swager assembly (206). The receiver-fastener turret (202) is selectively rotatable relative to the receiver-fastener housing (270) about a receiver-fastener-turret rotation axis (Z). The indexing-collet assembly (203) is selectively movable relative to the receiver-fastener housing (270) between an indexing-collet-assembly extended position and an indexing-collet-assembly retracted position along an indexing-collet-assembly axis (Y) that is parallel to the receiver-fastener-turret rotation axis (Z). The anvil (204) is selectively movable relative to the receiver-fastener turret (202) along an anvil axis (X) that is parallel to the receiver-fastener-turret rotation axis (Z). The receiver-fastener delivery assembly (205) is configured to operatively position receiver fasteners (506) for operative placement on shank fasteners (504), corresponding to the receiver fasteners (506). The swager assembly (206) is movable relative to the receiver-fastener turret (202) along a swaging axis (W) that is parallel to the receiver-fastener-turret rotation axis (Z).

An apparatus for binding to a select surface and a method of use thereof is provided. The apparatus comprises a body, a flexible member, and a recess. The body has a proximal surface configured with a fluid port. The flexible member has a cavity therein and is operatively coupled to the body to form a seal with the body. The flexible member is configured to expand responsive to an expansive pressure within the cavity. The recess is formed by the proximal surface and the flexible member. The fluid port is configured to facilitate generation of a binding pressure within the recess.

Workpieces that generate pressure by an extrusion media (6, 6a) and are deformed in this way for the secure connection of components (7, 8). In particular, an extrusion billet which comprises an extrudable material or material mixture in the interior thereof, which can be reversibly compressed by a compression die (4) penetrating into the material, such that billet can expand in diameter by increasing the internal pressure in the billet, which leads to a very secure, but reversible press fitting of the different types of components to be connected, in particular of shaft-hub connections for mechanical engineering.

A device for clamping a rotatably mounted shaft element including: a housing element having an annular housing portion wherein the shaft extends in the axial direction; an elastically deformable annular clamping ring element arranged in the annular housing portion, wherein the clamping ring has a cross-sectional profile with a first profile portion, extending radially inward and protrudes radially through an annular circumferential opening; and a pressure chamber formed in the annular housing has at least one pressure chamber portion arranged radially on the inner side adjacently to at least one second profile portion of the clamping ring; wherein the rotatably mounted shaft in a rest state clamped by frictional engagement with the first profile of the clamping ring protruding toward the shaft, and wherein the frictional engagement between the shaft and the first profile is releasable, the clamping ring is elastically deformable radially outward by pneumatic or hydraulic pressure chamber.

A threading bolt (1) for stacking sheets provided with at least one threading hole (2), in particular core sheets (3) of transformer cores, on a core stacking table (4), on a building platform, on a stacking device or the like, at least one threading bolt (1) being positionable on the core stacking table (4), on the building platform, on the stacking device or the like, wherein the outer diameter (D.sub.a) of the threading bolt (1) is adaptable to different inner diameters (d.sub.i) of the threading holes (2).
