I have a Time Saver top 30 wide belt sander. The rubber conveyor is separating at the seam. Time saver no longer supports this machine. Is there some type of adhesive I can use to patch this togeather, or another source for belts.
If it is a rough top conveyor make sure to stick with natural rubber. Also, if you buy a laced belt, make sure they skive away all the rubber on the seam and use the thinnest splice possible. Otherwise you can't dress the conveyor.
Endless is better if you are inclined to mechanical work.
I have had good luck repairing some sander conveyor belts with Hardman Urethane adhesive # 04024. It comes in a ready to mix package, and is similar to a 5 minute epoxy as far as thickness and application. This will not fix a belt that is going to split completely in half, but sometimes these belts seem to delaminate and start developing a flap. Like any glue, everything must be clean before you start. If you position the belt so it is at about 3 o'clock on the infeed table roller, the split will be more open so you can get the glue into the crack. Then advance the belt until it is horizontal so the glue does not drip and can set up.
Lay a heavy weight on top of the area, or put a big clamp on it to keep the repair flat. Slip waxed paper under the belt to avoid gluing the conveyor belt to the machine.
I would STRONGLY discourage you from using a "clipper laced" belt unless its only temporary. Yes it is less labor to install especially if you machine is in line with other equipment and access to pulling the bed assembly out is limited. However what is not taken into consideration is the damage the metal lacing does to your conveyor bed plates. As the metal lacing drags across your bed plates, you are creating friction, metal on metal. Its even worse when you load material on that seam. Now your forcing the metal lacing to create more friction on your bed plates from the pressure of your pinch rolls as well as the abrasive belt. The cost of grinding or installing new bed plates is not pretty. I have had customers spend thousands of dollars to repair the damage these belts create.
Depending where the separation is (on the rubber surface or on the canvas or both) will determine the repair. If the entire seam is separating, any repair you do will be temporary, In my experience once a weak spot is created in your conveyor belt, it's only a matter of time before it completely fails due to the tension used to keep the belt tight to the feed drive roll and also the"pressure" you create when sanding material. If the damage is only related to the top rubber layer, you can try cutting the delaminated/damaged area away and using silicone as a filler. The silicone will be pliable enough to follow the radius of your feed drive and take up rolls.
FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards(return to top)
WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
A valid email return address must be included with each message.
Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
Subject lines may be edited for length and clarity.
"Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.

Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards.
