Abstract
Abstract An automatic band-winding machine for a plurality of bands comprises winding heads, threading units having cutting blades, prewinding mechanisms, a band-deflecting station and a conveyor belt for carrying away the ready rolls. The winding heads, which are adapted to be driven through bevel gears and friction clutches are arranged opposite one another in one plane about a horizontal axis and are rotatable about this axis through 180*. Gravity clutches are provided for so that only the winding heads above the horizontal plane through the common axis are connected to the drive.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
355 words
An automatic machine for providing a plurality of rolls of wound bands comprising a supply of relatively wide band material, a row of parallel cutters operatively associated with said supply and engaged with said relatively wide band for slitting it into a plurality of relatively narrow bands, an array of winding devices corresponding in number to said narrow bands, a movable threading and guiding unit operatively engaged with each of said winding devices for threading and guiding the end of a narrow band onto each of said winding devices, a cutter on each of said threading and guiding units for severing said band after a predetermined length has been wound onto a roll upon said winding device, an array of supporting and deflecting rollers between said rollers and each of said threading and guiding units for supporting and guiding a predetermined length of said narrow bands from said feed rollers to each of said threading and guiding units, each of said winding device having a motion-transmitting device, a pair of heads for carrying roll cores extending from opposite sides of said motion-transmitting device for alternate disposition in alignment with said threading and guiding unit and a discharge station, said motion-transmitting device having drive means for rotating said winding heads when disposed in line with said threading and guiding units, indexing means on said motion transmitting device for successively rotating said heads from alignment with said threading and guiding unit to said discharge station, a winding starting casing operatively arranged for disposition about each of said winding heads when they are aligned with said threading and guiding units for guiding the starting end of said bands upon said cores when disposed upon said winding head, translating means connected to each of said winding starting casings for engaging them about said winding heads carrying a core to start the end of a band to be wound on said core and for removing said winding starting casing after a winding has been securely started upon said spool, and said threading and guiding unit being movably mounted to freely guide said winding upon said core in an increasing diameter.

An automatic machine for providing a plurality of rolls of wound bands comprising a supply of relatively wide band material, a row of parallel cutters operatively associated with said supply and engaged with said relatively wide band for slitting it into a plurality of relatively narrow bands, an array of winding devices corresponding in number to said narrow bands, a movable threading and guiding unit operatively engaged with each of said winding devices for threading and guiding the end of a narrow band onto each of said winding devices, a cutter on each of said threading and guiding units for severing said band after a predetermined length has been wound onto a roll upon said winding device, an array of supporting and deflecting rollers between said rollers and each of said threading and guiding units for supporting and guiding a predetermined length of said narrow bands from said feed rollers to each of said threading and guiding units, each of said winding device having a motion-transmitting device, a pair of heads for carrying roll cores extending from opposite sides of said motion-transmitting device for alternate disposition in alignment with said threading and guiding unit and a discharge station, said motion-transmitting device having drive means for rotating said winding heads when disposed in line with said threading and guiding units, indexing means on said motion transmitting device for successively rotating said heads from alignment with said threading and guiding unit to said discharge station, a winding starting casing operatively arranged for disposition about each of said winding heads when they are aligned with said threading and guiding units for guiding the starting end of said bands upon said cores when disposed upon said winding head, translating means connected to each of said winding starting casings for engaging them about said winding heads carrying a core to start the end of a band to be wound on said core and for removing said winding starting casing after a winding has been securely started upon said spool, and said threading and guiding unit being movably mounted to freely guide said winding upon said core in an increasing diameter.
Claim 3
Dependent Claim
38 words
A machine according to claim 1, wherein the threading and guiding units are pivotal in the horizontal plane and are pivoted so that they are always directed tangentially of the roll diameter, whatever the diameter of the roll.
Claim 4
Dependent Claim
67 words
A machine according to claim 1 wherein each of the rolls has a tubular core each winding starting casing comprises a vertically displaceable hollow cylinder having a threading slot and a pressure roller opening therein, the cylinder being inverted over the tubular core disposed upon the winding head in the working position and being removed from the winding head in the rest position at said discharge station.
Claim 5
Dependent Claim
36 words
A machine according to claim 1 wherein a conveyor belt is arranged at said discharge station and said conveyor belt is coated on one side with a velours into which deposited rolls are adapted to sink.
Claim 6
Dependent Claim
128 words
A machine according to claim 1 wherein the threading and guiding units are disposed vertically over the winding heads, said motion-transmitting means comprising a diffErential gear the pair of winding heads being mounted on opposite sides of the differential gear disposed below the threading and guiding unit, rotating means connected to the differential gear for disposing one of the winding heads operatively adjacent the threading and guiding unit and the other below, a gravity clutch connected between each winding head and the differential gear whereby the winding head disposed above the differential gear and operatively adjacent the threading and guiding unit is operatively connected for transmitting rotation between the differential gear and the upper winding head and for disconnecting the lower winding head from the differential gear drive.
Claim 7
Dependent Claim
53 words
A machine according to claim 5 wherein each of the rolls have tubular cores and each of the winding heads includes a releasable clutch for engaging the cores to wind the bands or webs about them in the upper position and for releasing them in the lower position to discharge the wound rolls.
Claim 8
Dependent Claim
47 words
A machine according to claim 3 wherein the pressure roller includes automatic means for actuating the axial removal of the hollow cylinder from the winding head and partially wound rolls to permit the rolls to be subsequently wound to a final size larger than the hollow cylinder.
Claim 9
Dependent Claim
19 words
A machine according to claim 5; wherein each of the threading units includes guiding rollers and friction drive rollers.
Claim 10
Dependent Claim
17 words
A machine according to claim 1 wherein the motion-transmitting means are each connected on a common shaft.
Claim 11
Dependent Claim
16 words
