Tape lamination head with tape tension control system
A tape lamination head for applying composite tape onto a mold or mandrel amid the formation of a composite workpiece. The tape lamination head is but one component of a larger tape lamination machine and assembly. Among its components, the tape lamination head includes a tape supply reel, a backing paper take-up reel, and a tape tension control system. The tape tension control system has a first dancer roller assembly located downstream of the tape supply reel and has a second dancer roller assembly located upstream of the backing paper take-up reel. The first dancer roller assembly can include a first roller, a first guide, a first actuator, a first lock, and a first position sensor. The second dancer roller assembly can include a second roller, a second guide, a second actuator, a second lock, and a second position sensor.

Web tension control
The current invention is generally directed to apparatuses and methods for controlling tension and tension disturbances in a web being continuously unwound from a roll of spirally wound web material. In accordance with the present disclosure, a rotary dancer mechanism is used for applying active and variable forces to a moving web in response to irregularities, such as variations in tension. In one aspect, the apparatus and method of the present disclosure may be used to attenuate undesired disturbances in the web as the web is being fed into a process.
Method and apparatus for registering images of histological sections
An automated tissue section slicing, staining, and imaging system efficiently registers full-resolution tissue section images by applying scaled transformation matrices computed to register downsampled tissue section images to the full-resolution tissue section images.

System for supporting a reel of stamping foil, an unwinder module, a stamping machine, and a method for positioning a reel
A system for supporting a reel of stamping foil (2) that is mounted rotatably, includes: two flanges (9, 9) connected to the shaft of the reel (2, 2) that is positioned between the flanges, each flange having a rotary shaft extending outward of the reel; two end walls (7, 7) mounted spaced apart on a guide surface (3), each wall end having at least one upwardly oriented notch (10, 10) arranged to receive the shaft of each flange (9, 9); and a brake (13) which cooperates with and slows the rotation of the reel (2).
Medium winding device and printing system
The medium winding device includes a winding shaft, a drive unit for winding the medium around the winding member, a rotating member rotatably disposed, a tension applying member which moves as the drive unit is driven or stopped, a position detecting unit for detecting the position of the tension applying member, an output changing unit, a control unit that determines whether slippage occurs between the winding shaft and the winding member based on the position of the tension applying member and the result of output change by a rotation of the winding shaft. Further, the drive unit includes a torque limiter.
WEB CONVEYING DEVICE
A web conveying device configured to convey a web and rewind the web into a roll includes: a moving roller arranged between a send-in port for the web and a rewinding roll which is the web rolled, the moving roller configured to be movable in an up-down direction to apply tension to the web or release the tension; and a controller configured to perform control of moving the moving roller to an upper limit position in the up-down direction in an operation of stopping conveyance of the web.
Method for adapting at least one winding parameter of a winding device
The invention relates to a method for adapting at least one winding parameter of a winding device during winding of a film web on a winding core, having the following steps: conveying of the film web along a measuring path between a first driven roll and a second driven rollincreasing of the web tension of the film web between the first roll and the second rollcontinuous detecting of the drive parameters of the first roll and of the second roll at least in the form of the torque and the circumferential speed, determining of a stress-strain diagram from the detected drive parametersadapting of at least one winding parameter of the winding device on the basis of the determined stress-strain diagram in order to achieve a defined elongation of the film web during winding on the winding core.
