Abstract: A device for unwinding a web of material from a reel. It has two supporting arms that are positioned separated and extending across the web, that can be pivoted up, and that can accommodate and hold the reel in such a way that it can be rotated. To improve a generic device to the extent that it will be simple in design and take up little space, the pivoting bearings for the supporting arms are moved between two positions that extend horizontally and mutually displaced across the axis of rotation.

Abstract: A core holder for a winding apparatus for winding webs of material in the paper, printing, and textile industries, including a rotatable core-receiving spindle or mandrel, and a segmented friction core holder, expandable outwardly at selected points, by which the core is tightly gripped when the mandrel is turning, and which readily releases its grip on the mandrel upon a simple manual maneuver by the operator, and is readily removable with little force. The core holder assembly is round, but the mandrel-receiving hole has segmented arcs which are not concentric with the outer surface of the core holder, creating stops which limit the movement of the segments about the mandrel.

A roll core with the finished foil roll can be received at its ends by lowering arms. It can be deposited on a discharge level by means of a lowering-arm drive. The lowering arms can again be raised with the aid of the lowering-arm drive. For each of the lowering arms, the lowering-arm drive has a lowering cam plate, these being identically built, congruently arranged and provided with an outer leading edge, which is basically shaped as a numeral 6. The lowering arms are guided on the leading edge by means of a guide element. The lowering cam plates are driven by a simple electromotor.

Abstract: An intermittently operating unwinding apparatus has a splicing unit with a cross member which is movable against and at right angles to the web expiring from a winding roll. With a separating device positionable against the cross member from the other side of the web, the web is separated by lifting the empty spool mounted in the unwinding apparatus out of its unwinding position. A new parent roll whose web beginning is provided with an application of adhesive is transported by means of a conveyor to the unwinding position and the web beginning positioned relative to the splicing unit. The splicing unit holding the separated web-end at the cross member is radially moveable against the new parent roll, where the web-end meets the beginning of the web and is attached by means of the adhesive. The web length required to lead the web-end to the new roll is made ready by a dancer roller.

Abstract: Apparatus for controlling tension in a movable web includes a frame supporting a web supply roll, and a torque motor connected to the supply roll. The web is supported along a web path. Web position is measured by a dancer roll biased against the web. A signal representative of the web position is generated and supplied to a control system, which receives the position signal and generates in response a torque signal representative of a torque value to be applied to the roll to cause the actual web position to equal a nominal position. The control system is connected to the torque motor to control the motor in accordance with the torque signal.

Abstract: A safety nut assembly is provided for mounting to the carriage of a backstand apparatus to which a large roll of paper is rotatably mounted. The backstand apparatus includes an inclined screw spindle to which the carriage is threadedly engaged, such that rotation of the screw spindle moves the carriage therealong. The safety nut assembly comprises a mounting portion for secure but removable mounting to the carriage of the backstand. The safety nut assembly further includes a threaded aperture for threadedly engaging the inclined screw spindle. The threaded grooves of the threaded aperture in the safety nut assembly are larger than the threads of the primary weight-bearing bushing in the carriage. Thus, the safety nut assembly will assume a weight-bearing function only upon failure of the primary bushing in the carriage.

Abstract: A film cassette is disclosed wherein a spool includes two coaxial core pieces having a convoluted film roll coiled about them, whose outermost convolution is a film leader, and respective flanges fixed to the core pieces which radially extend over the opposite sides of the film roll. At least one of the core pieces is supported for movement axially toward the other one to move at least one of the flanges axially toward the other one to provide axial clamping forces at the opposite sides of the film roll. A film stripper-guide is received between the outermost convolution and the next-inward convolution of the film roll to strip the outermost convolution from the flanges and guide it through a film passageway to the exterior of the cassette shell responsive to rotation of the spool in a film unwinding direction during application of the axial clamping forces.

Abstract: A device for winding up a foil web, particularly a foil web of synthetic material, into a foil roll on a roll core, has two swivel arms having roll-core receiving portions at their ends, a contact roller, and an actuating cylinder-piston arrangement for the swivel arms and the roll core drive. The swivel arms are swung according to the indication of the increasing diameter of the foil roll. In the area of the contact roller, a winding device with two swingable winding arms is arranged. A roll-core magazine is assigned thereto, having two magazine disks, which are oppositely located and rotatable about a horizontal axis and have corresponding receiving portions for the roll-core ends. To each magazine disk, a basically L-shaped guiding element is assinged which on the vertical flank of the L has an arched leading edge following the path of the roll-core receiving portions, which--over an assembly trough--continues with a downwardly inclined level which is a discharge edge.

Abstract: The device has a box-like body rotatably supporting a spool for winding one or more cables, a pivot rigidly connected to the spool, and a knob engaging the pivot in screw thread engagement relationship for actuating the spool. The pivot is connected to a toothed ring which interacts with a ratchet mechanism for preventing cable from being unwound from the spool upon a rotational movement being imparted thereto by turning the knob in one direction, and which permits cable to be unwound from the spool upon turning the knob in another direction. A pawl element has one portion which slides within a helical seat defined by a flange rigidly associated with the spool, and another portion which slides within a guide formed radially on the box-like body, for limiting the stroke of the rotational movement of the spool.

Abstract: A film cassette is disclosed wherein a film spool is rotatable within the cassette shell, a convoluted film roll whose outermost convolution is a film leader is coiled about the spool, a pair of film constraining flanges are coaxially arranged on the spool to radially confine the film leader to prevent the leader from substantially contacting an interior wall of the cassette shell, and a film stripper-guide is received between a leading end of the film leader and the next-inward convolution of the film roll succeeding the leader to remove the leader from the flanges and guide it through a film passageway to the exterior of the cassette shell responsive to rotation of the spool in a film unwinding direction.

Abstract: A reel for wire with a rotary basket, a reel bottom which can be raised and lowered and a spiral tube which can be raised and lowered and swiveled. The reel bottom has an axially directed projection whose circumference corresponds to the inner diameter of the wire coil to be coiled. The spiral tube is connected to a spiral tube cylinder which also has an outer diameter which corresponds to the inner diameter of the coil. The reel can be operated even at high circumferential speeds without damaging the wire.

Abstract: A film cassette is disclosed wherein a spool having a convoluted film roll coiled about it, whose outermost convolution is a film leader, includes two coaxial core pieces adapted to telescopically receive one another and respective flanges fixed to the core pieces which radially cover the opposite sides of the film roll. When the spool is initially rotated in a film unwinding direction, rotation responsive means moves at least one of the core pieces axially toward the other one to cause the flanges to clamp the film roll at its opposite sides and a film stripper-guide is received between a leading end of the film leader and the next-inward convolution of the film roll succeeding the leader to remove the leader from the flanges and guide it through a film passageway to the exterior of the cassette shell.

Abstract: An intermittently operating unwinding apparatus has a separating device with which a web-end is formed on the lifting-out of an empty spool from the guide ways of an unwind unit. A holding device holds the web-end in a plane which extends parallel to the guide ways, on which a new winding roll located in waiting position rests with its roll axle. The machine has a splicing unit with a cross member arranged parallel to the guide ways to which the beginning of the web of the new parent roll can be joined. During transport of the new parent roll out of the waiting position into its unwinding position the splicing unit is moved by dogs engaging at the roll axle against the holding device and the web-beginning joined to the web-end.

Abstract: A film cassette is disclosed wherein a film spool having a filmstrip coiled about it is selectively rotatable in opposite directions to advance a leader portion of the filmstrip through a film passage slit to the outside of the cassette shell and to return the leader portion to the inside of the cassette shell. A pile-like material, such as velvet or plush, consisting of short close flexible fibers is secured to the cassette shell along the film passage slit to prevent ambient light substantially from entering the slit. The leader portion has at least one hole adapted to receive a sufficient number of the fibers to allow the fibers to engage the leader portion to prevent its casual creep rearward in the film passage slit. The fibers have a resistance to displacement from the hole which can easily be overcome by rotating the film spool to move the leader portion.
