An automated fiber bundle placement apparatus includes a supply device, a placement head, and an articulated robot. The articulated robot includes a head swing mechanism and a guide mechanism. The guide mechanism includes a position changing mechanism which includes a support member for supporting a tow guide, and which displaces the tow guide corresponding to a change in a position of an introduction section by a head swing mechanism.

A winding section of a filament winding apparatus winds a fiber bundle around a filament-wound member. A tension acquisition part acquires a detected winding-tension value. A supply-speed acquisition part acquires a detected supply-speed value. A storage part stores correlation information in which an allowable determination range of winding tension is set in relation to the supply speed. A determination part determines whether the winding of the fiber bundle is successful or unsuccessful by comparing detected-value information, including the detected winding-tension value and the detected supply-speed value associated with each other, with the correlation information.

The present invention relates inter alia to an apparatus for providing a coiled collagen carrier. An apparatus according to the invention preferably comprises a device for applying moisture to a collagen carrier prior to coiling of the collagen carrier and a coiling device. The coiling device preferably comprises rotatable gripping means for gripping the collagen carrier along an edge and coiling the collagen carrier, and a support device supporting the collagen carrier while being coiled. In another aspect, the invention relates to a production facility wherein an apparatus according to invention is arranged.

A method for producing wound hollow profiles having variable curvatures and cross-sections. In this case, a core having at least one curvature or cross-sectional change is moved in a translatory manner relative to a system having at least a first and a second fibre feed which cause the formation of an axial fibre reinforcement and at least one first wound layer.

A compacter that includes a compacting roller assembly, borne by a support element. The roller assembly includes a straight central shaft, having a longitudinal axis, and a plurality of compacting rollers, mounted parallel to one another about the central shaft, each compacting roller having a peripheral surface rotating around the central shaft about a roller axis. The longitudinal axis of the central shaft is parallel to the central axis of the support element. Each roller axis is inclined by a nonzero incline angle relative to the longitudinal axis of the central shaft.

A paint roller manufacturing system and method are described. In an embodiment, an inner strip of material and an outer strip of material are wound about a mandrel in offset relation. The inner strip of material and the outer strip of material each comprise material that results in a final paint roller which shrinks by less than 2.5 percent of the final paint roller axial length, or which has shrinkage that varies by less +/−0.1%, upon hardening and setting. An adhesive is applied to at least a portion of the outer strip as it is wound about the mandrel. A length of fabric is wound about at least the outer strip to form a paint roller tube, and compression is applied to the paint roller tube while advancing the paint roller tube in a direction parallel to the mandrel. A precision measuring or sensing device is used to control a cutting device causing the cutting device to cut the advancing paint roller tube into pre-selected lengths prior to the paint roller tube hardening and setting.

A sash (62) of a window opening up to 180 and capable of tilting is mounted onto a fixedly installed frame profile (63) and houses a pair of superimposing sashes that fit tightly therein when in closure position, i.e. an upper stationary sash (65) and a lower movable-divertible sash (64), each of the sashes (64,65) provided with laterally extending shafts (49) for connection with sash (62), roller wheels (50) provided onto the shafts (49) of sash (64) that roll within a predefined path created by insert guide profile members (19) and diverter guide members (66,68) to alternately bring sash (64) in a position of superimposing sash (65) and a position of alignment with the same. Lifting mechanisms (46) provided with a regulatory screw (84) for adjusting the pretension of a spring component thereof and thereby the force required by the user for moving the sash (64) are installed within the vertically extending sides of the sash (62).

The disclosure relates to a tape laying apparatus configured to lay prepreg tape to mould surface. The tape laying apparatus includes a tape supply spool, a compaction head, a cutting tool and at least one travel distance adjustment component. The tape supply spool is configured for the prepreg tape to be wound thereon. The compaction head is configured for delivering the prepreg tape to the mould surface from the tape supply spool. The cutting tool is movable along a cutting path. The cutting tool is configured to cut the prepreg tape passing through the cutting path. The at least one travel distance adjustment component is movably located between the cutting path and the compaction head and configured to push the prepreg tape passing through the cutting path so as to increase or decrease a travel distance of the prepreg tape from the cutting path to the compaction head.

The invention relates to a fastening element for fastening to a workpiece, said fastening element comprising at least a first workpiece element having a first opening and a second workpiece element having a second opening aligned with the first opening, wherein the fastening element has a first contact section having a first contact surface for contact with a region of the first workpiece element surrounding the first opening and a second contact section having a second contact surface for contact with a region of the second workpiece element surrounding the second opening, with the first contact section and the second contact section being connected to one another by means of a reshaping section, and with a rivet section extending from the second contact section in a direction facing away from the reshaping section. The invention further relates to a corresponding component assembly and to a method of manufacturing such a component assembly.

Disclosed herein is an automated fiber placement system that comprises a robot, an end effector, and a creel assembly that is coupled to the robot and movable with the robot. The creel assembly comprises a spool of a tow and a tow tensioner. The tow tensioner comprises an arm assembly that is pivotable toward and away from a tow direction between a forward position and a rearward position, inclusive, and configured to secure the tow from the spool as the tow unwinds from the spool and moves in the tow direction. The tow tensioner also comprises a biasing member that is coupled to the arm assembly and configured to bias the arm assembly into a neutral position between the forward position and the rearward position. The tow tensioner additionally comprises a potentiometer that is coupled to the arm assembly and configured to detect a position of the arm assembly.
