Abstract
Abstract A fabric printing machine having a conveyor belt for supporting a fabric to be printed. A drive unit is connected to the belt, and a control mechanism coacts with the belt and the drive unit for permitting intermittent unidirectional advancing movement of the belt through a selected distance. The drive unit includes a first drive for advancing the belt at a fast speed and a second drive for advancing the belt at a slowspeed. The control mechanism includes a belt engaging device adapted for gripping engagement with the belt for causing synchronous movement of the belt and engaging device during the advancing movement. The control mechanism also includes means for activating the belt engaging device and for causing the first and second drives to be sequentially connected to the belt for moving the belt at fast speed through a first preselected distance and thereafter moving the belt at slow speed through a second preselected distance. A return device releases and returns the belt engaging device to its initial position.

Claim 1
Independent Claim
338 words
In a fabric printing machine having a conveyor belt for supporting thereon a fabric to be printed, a drive unit interconnected to said belt for moving same, and a control mechanism coacting with said belt and said drive unit for permitting intermittent unidirectional advancing movement of said belt through a selected distance, comprising the improvement wherein: said drive unit including first drive means for advancing the conveyor belt at a fast speed and second drive means for advancing the conveyor belt at a slow speed; elongated guide means disposed adjacent and extending substantially parallel to a portion of said conveyor belt; said control mechanism including a belt engaging device slidably supported on said guide means, said belt engaging device including gripping means adapted for gripping engagement with said belt for causing synchronous movement of said belt and said engaging device during the advancing movement of said belt; stop means coacting with said guide means for determining the initial position of said belt engaging device; said control mechanism also including first means for causing activation of said gripping means so that same grippingly engages said belt when said belt engaging device is in said initial position and for causing said first drive means to be drivingly connected to said belt for moving said belt at said fast speed; first switch means for deactivating said first drive means and interconnecting said second drive means to said belt, after said belt engaging device and said belt have been moved through a first preselected distance away from said initial position, for permitting further advancing movement of said belt at said slow speed; second switch means for stopping said conveyor belt and said belt engaging device after they have been moved through a second preselected distance beyond said first preselected distance, said second preselected distance being small in comparison to said first preselected distance; and return means for releasing said gripping means from said belt, after displacement through first and second preselected distances, and returning said belt engaging device to said initial position.
Claim 2
Dependent Claim

In a fabric printing machine having a conveyor belt for supporting thereon a fabric to be printed, a drive unit interconnected to said belt for moving same, and a control mechanism coacting with said belt and said drive unit for permitting intermittent unidirectional advancing movement of said belt through a selected distance, comprising the improvement wherein: said drive unit including first drive means for advancing the conveyor belt at a fast speed and second drive means for advancing the conveyor belt at a slow speed; elongated guide means disposed adjacent and extending substantially parallel to a portion of said conveyor belt; said control mechanism including a belt engaging device slidably supported on said guide means, said belt engaging device including gripping means adapted for gripping engagement with said belt for causing synchronous movement of said belt and said engaging device during the advancing movement of said belt; stop means coacting with said guide means for determining the initial position of said belt engaging device; said control mechanism also including first means for causing activation of said gripping means so that same grippingly engages said belt when said belt engaging device is in said initial position and for causing said first drive means to be drivingly connected to said belt for moving said belt at said fast speed; first switch means for deactivating said first drive means and interconnecting said second drive means to said belt, after said belt engaging device and said belt have been moved through a first preselected distance away from said initial position, for permitting further advancing movement of said belt at said slow speed; second switch means for stopping said conveyor belt and said belt engaging device after they have been moved through a second preselected distance beyond said first preselected distance, said second preselected distance being small in comparison to said first preselected distance; and return means for releasing said gripping means from said belt, after displacement through first and second preselected distances, and returning said belt engaging device to said initial position.
Claim 3
Dependent Claim
48 words
A machine according to claim 1, further including adjustment means coacting with said stop means for permitting the location of said stop to be selectively varied, whereby said initial position can be varied to permit variation over the selected distance through which said belt is unidirectionally intermittently advanced.
Claim 4
Dependent Claim
48 words
A machine according to claim 1, wherein said first and second drive means respectively include first and second motor means, said first and second clutch means respectively associated with said first and second motor means for drivingly interconnecting the first and second motor means to the conveyor belt.
Claim 5
Dependent Claim
77 words
A machine according to claim 3, wherein activation of said first switch means causes disengagement of said first clutch means, wherein activation of said second switch means causes disengagement of said second clutch means, said conveyor belt being supported on and driven by a driving roller, said driving roller being drivingly interconnected to said first and second clutch means, and brake means associated with said driving roller and automatically actuated upon activation of said second switch means.
Claim 6
Dependent Claim
68 words
A machine according to claim 1, wherein said gripping means includes a pair of relatively movable jaws which are positioned adjacent one edge of said belt and are disposed on opposite sides thereof, said jaws being relatively movable towards one another for gripping the edge of said belt therebetween, said belt engaging device having an activator associated therewith for causing activation of said first and second switch means.
Claim 7
Dependent Claim
69 words
A machine according to claim 5, wherein said jaws are pneumatically actuated for relatively moving same toward one another for grippingly engaging said belt, an elongated flexible conduit connected to said belt engaging device for supplying pressure fluid thereto for activating said jaws, and a driving device connected to said elongated flexible conduit for moving same to cause return movement of said belt engaging device to said initial position.
